Answer 1

Answer:

7. adjacent

8.127°

Step-by-step explanation:

adjacent angles on a straight line add up to 180°

180-53=127°

Answer 2

Answer:

they are supplementary

x = 127

Step-by-step explanation:

supplementary angles equal 180 degrees so you would do: 180 - 53 to find x

18 units^2

Step-by-step explanation:

There are two trianges each with a base of 3 and a height of 3, making each 4.5 units^2 and together, 9. Add the area of the triangles with the square to get 18.

Answer:

A = 18 cm²

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases )

Here h= 3, b₁ = 3 and b₂ = 9 , then

A = [tex]\frac{1}{2}[/tex] × 3 × (3 + 9)

= 1.5 × 12

= 18 cm²

Liam scored 22 out of 30 marks in Algebra, 35 out of 40 marks in science, and 89 out of 100 marks in mathematics. In which subject his percentage of his marks best?

Answers

Answer:

maths

Step-by-step explanation:

we have found out 89 out of 100.

35 out of 40 = 87.5 out of 100 (100÷ 40 = 2.5 | 2.5 x 35)

as we repeat the same formula again

22 out of 30 goes somewhere near 73.

which means his highest marks were in math!

his best percentage is 89/100

•What is the value of X?
•What is the measure of angle C?
Also 50 points answer because I feel like it lol.

Answers

Answer:

solution given:

3(x+2)+35°+52°=180°[sum of interior angle of a traingle is 180°]

3(x+2)=180-87

x+2=93/3

x+2=31

x=31-2=29°

value of x=29°

again

<C=3(29°+2)=93°

the measure of angle C=93°

Answer:

x = 29

angle c = 93

Step-by-step explanation:

Angles in a triangle add up to equal 180

That being said we create an equation to solve for x

180 = 3(x+2) + 52 + 35

Now we solve for x using basic algebra

step 1 distribute the 3 to ( x and 2 )

3 * x = 3x

3 * 2 = 6

now we have 180 = 3x + 6 + 52 + 35

step 2 combine like terms

6 + 52 + 35 =93

now we have 180 = 93 + 3x

step 3 subtract 93 from each side

93 - 93 cancels out

180 - 93 = 87

now we have 87 = 3x

step 4 divide each side by 3

3x / 3 = x

87 / 3 = 29

we're left with x = 29

Now we want to find the measure of angle C

To do so we plug in 29 for "x" in 3 ( x + 2)

3 ( 29 + 2 )

29 + 2 = 31

3(31) = 93

Hence angle c = 93

Step-by-step explanation:

The goalie on the Iceblades hockey team saves (blocks) 73% of the opponent's shots. With 10 minutes to go, the Iceblades are ahead by one goal, and they will win if the other team does not score.

The other team takes 5 shots in the final 10 minutes. The Iceblades do not score any more goals.

The table shows pairs of random digits. The pairs in each group simulate the 5 shots taken by the opponent.

Answer the questions to estimate the probability that the Iceblades will win the game.

1. The paired digits 00 to 99 represent 100 shots.

Let 00 to 72 = a shot that is saved. Which digits represent a goal scored? Explain.

Write your answer in the space below.

2. Each group represents the 5 shots taken by the other team. To win the game, the Iceblades cannot let the other team score any goals.

For a group to be a success, how many of the 5 shots does the goalie need to save?

Write your answer in the space below.

3. Group 1 is a success. Explain why.

Write your answer in the space below.

4. In this simulation, which groups are successes? How many successes are there in the 10 groups?
