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
X= -46 and y = -40 I worked it out I might be wrong
Answer:
if your finding x then it's 45°
Answer:
h = 36 units
Step-by-step explanation:
A = 1/2bh
72=1/2(4)h
72=2h
h=36 units
