Answer:

see explanation

Step-by-step explanation:

Since the triangles are congruent then corresponding angles are congruent.

Thus ∠D = ∠A and substituting values

2x = x + 31 ( subtract x from both sides )

x = 31

Hence

∠A = x + 31 = 31 + 31 = 62

∠D = 2x = 2 × 31 = 62

I need help with this problem
kolbaska11 [484]
It’s 20 I believe. All together it should be 160 so you add 118 and 22 to get 140. Then subtract that from 160 and you get 20.

Given the exponential equation 4x = 64, what is the logarithmic form of the equation in base 10?
zysi [14]
4^{x} = 64

By taking <span>logarithmic of base 10

∴ </span><span>log 4^{x} = log 64

∴ x log 4 = log 64

∴ x =  \frac{log \ 64}{log \ 4}
note: we don't need to write the base in case of the base =10

∴ The correct choice is
</span><span>x = log base 10 of 64, all over log base 10 of 4</span>

Given that PQRS is a square, find x and y.
Dovator [93]
Every angle of a square equals 90 degrees.

2x - 4 = 90              3y + 6 = 90
2x = 90 + 4              3y = 90 - 6
2x = 94                    3y = 84
x = 94/2                     y = 84/3
x = 47                        y = 28

so x = 47 and y = 28
