Your answer is 2/3 hope this helps
M∠A = 133°.
Opposite angles in an inscribed quadrilateral are supplementary, so we have
(4x+5)+(x+15) = 180
Combining like terms gives us
5x + 20 = 180
Subtract 20 from both sides:
5x+20 - 20 = 180 - 20
5x = 160
Divide both sides by 5:
5x/5 = 160/5
x = 32
Substitute this into our expression for ∠A:
4(32) + 5
128 + 5
133
Answer: H
Step-by-step explanation:
For this case we must simplify the following expression:
We rewrite the expression:
We eliminate common terms:
For division of powers of the same base, the same base is placed and the exponents are subtracted:
By definition of properties of powers and roots we have:
So:
