Sorry if this doesn't help
This is my work from a while ago
Answer:
A: 90° B: 67° c: 23° D: 67° E: 90° F: 23°
Step-by-step explanation:
A: 90° known
B: 67° 90-∠C=90-23=67
C: 23° known
D: 67° similar triangle property
E: 90° known
F: 23° similar triangle property
P + 7 / 12 = 3
x12 x12
p + 7 = 36
-7 -7
p = 29
H(x) = -x² - 4
i(x) = 2x + 3
h(i(5)) = -(2(5) + 3) - 4
h(i(5)) = -(10 + 3) - 4
h(i(5)) = -(13) - 4
h(i(5)) = -13 - 4
h(i(5)) = -17
