Answer:
x = ±2sqrt(15)
Step-by-step explanation:
x^2 = 60
Take the square root of each side
sqrt(x^2) = ±sqrt(60)
x = ±sqrt(60)
x = ±sqrt(4 *15)
x = ±2sqrt(15)
Answer:
37 degree
Step-by-step explanation:
AB = 180 it is a straight line
ACD = 90 degree
DE+ DCB are complimentary angles they add up to 90 they dont need to be next to each other.
DE = 53 deg
DCB = 90-53= 37 degree
g = 37 and F is its vertical angle as they share the same corner point and lay opposite each other and each have same angle 37 degree.

<u>Step 1: Define expression</u>
64 + [40 ÷ (4 - 7 + 8)] - 10
<u>Step 2: Evaluate</u>
- Brackets - Parenthesis - Subtract: 64 + [40 ÷ (-3 + 8)] - 10
- Brackets - Parenthesis - Add: 64 + [40 ÷ 5] - 10
- Brackets - Divide: 64 + 8 - 10
- Add: 72 - 10
- Subtract: 62
And we have our final answer!
