∡ABD and ∡BAD = ∡55°
As we can see Δ ABD is isosceles
so,
∡ABD = ∡BAD (let us assume them to be ∡F)
Therefore
∡ABD+∡BAD+∡ADB = 180°
2∡F+∡ADB = 180°
2∡F + 70° = 180°
∡F = 55°
∡ABD = ∡BAD = 55°
Now
∡ABD + ∡CBD = 180° (Supplementary Angles)
55° + ∡CBD = 180°
∡CBD = 125°
As the sum of all the angles in a triangle is 180°
∡BDC +∡DCB +∡CBD = 180°
∡BDC + 29° +125° = 180°
Hence
∡BDC = 26°

Write the equation of each circle. center at (-4, 3), radius 9
Answers
Answer:
(x-h)²+(y-k)²=r²
putting respective value
(x--4)²+(y-3)²=9²
(x+4)²+(y-3)²=81
Answer:
(x + 4)^2 + (y - 3)^2 = 9^2
Step-by-step explanation:
Here our center is at (-4, 3), so h = -4 and k = 3. Radius, r, is 9.
Insert these values into the standard equation of a circle centered at (h, k) with radius r:
(x - h)^2 + (y - k)^2 = r^2 becomes:
(x + 4)^2 + (y - 3)^2 = 9^2

Issac shovels driveways to earn money. He can shovel 14 driveways in 8 hours. Earns $25.00 for each driveway. Issac is saving up to buy a new computer that costs $831.25. How many hours does Issac need to work to earn enough money to purchase the computer?
Answers
Answer:
19 hours
Step-by-step explanation:
Issac shovels driveways to earn money. He can shovel 14 driveways in 8 hours. Earns $25.00 for each driveway. Issac is saving up to buy a new computer that costs $831.25. How many hours does Issac need to work to earn enough money to purchase the computer?
Step 1 find the number of driveways to shovel
25x = $831.25
x = $831.25/25
= 33.25 driveways
Step 2
He can shovel
14 driveways = 8 hours
33.25 driveways = x
Cross Multiply
14x = 8 × 33.25
x = 8 × 33.25/14
x = 19 hours

A squirrel burrowed 12 holes in 3 minutes. How many holes could the squirrel burrow in 12 minutes?
Answers
Answer:
48 holes
Step-by-step explanation:
We know that in 3 minutes, a squirrel managed to bury 12 holes. Now, what if there were 12 minutes?
To solve this, we need to see the increase in minutes and implement the same thing to the holes.
So how do we get 3 minutes to 12 minutes? By multiplying 3 by 4, now do the same for the amount of holes the squirrel burrowed in 3 minutes.
3min * 4 = 12min
12 holes * 4 = 48 holes
