Answer:
D. 28°
Step-by-step explanation:
Since ∆FGH is congruent to ∆QRS, it follows that:

Thus:
(Substitution)
Collect like terms


Divide both sides by -1
x = 9

Plug in the value of x
Step-by-step explanation:
x=4kn+4km
x-4kn=4km
divide both sides by 4k
m=x-n
Answer:
This is an equation of tangent and normal to the curve
Answer:
I hope it helps it was the best I can do.
Step-by-step explanation:
-x12 + x7 = 0
Factorization:
−x7(x − 1)(x4 + x3 + x2 + x + 1) = 0
Solutions based on Jenkins–Traub algorithm:
x1 = … = x7 = 0
x8 = 1
x9 = −0.809017 − 0.587785i
x10 = −0.809017 + 0.587785i
x11 = 0.309017 − 0.951057i
x12 = 0.309017 + 0.951057i
Let
x------> height of Leon's older brother
y------> height of Leon
Convert mixed number to an improper fraction

we know that
-----> equation A
-----> equation B
substitute equation A in equation B

Convert to mixed number

therefore
<u>the answer is</u>
