8.1• 10^10. U need to move the decimal to the right 10 places. Then compare from the other things from the problem.
Step-by-step explanation:
Answer:
Step-by-step explanation:
You haven't given us a diagram of your figure. Assume it is like the one in the image below.
The formula for the area of a parallelogram is
A = bh
1. Determine the height of the parallelogram
Notice that the angle is 45°. That makes the triangle an isosceles right triangle, so we can use Pythagoras' Theorem.
h² + h² = (6√2)²
2h² = 36 × 2 = 72
h² = 36
h = 6
2. Calculate the area of the parallelogram
Answer:
see explanation
Step-by-step explanation:
Using the Addition formula for sine
sin(x ± y) = sinxcosy ± cosxsiny
Consider the left side
sin(360 - Θ ), then
= sin360°cosΘ - cos360°sinΘ
= 0 × cosΘ - 1 × sinΘ
= 0 - sinΘ = - sinΘ → verified
EC bisects so m<BEC = m<CED
11x - 12 + 2(4x + 1) = 180
11x - 12 + 8x + 2 = 180
19x - 10 = 180
19x = 190
x = 10
m<AEB= 11x - 12 = 11(10) - 12 = 98
m<CED = 4x+1 = 4(10) + 1 = 41
m<BEC = m<CED = 41
so
m<AEC = m<AEB + m<BEC
m<AEC = 98 + 41
m<AEC =139
answer
m<AEC =139
