Answer:

m∠EFH = 21°
m∠EFG = 83°
Step-by-step explanation:
We know that m∠EFH + m∠HFG will be equal to m∠EFG.
Since we know the values of each, we can make the equation:

Let's solve for x by isolating it on one side.
Combine like terms:

Subtract 11 from both sides:

Subtract 5x from both sides:

Divide both sides by 13:

Now that we know the value of x, we can substitute it inside the formulas for m∠EFH and m∠EFG.
m∠EFH:

m∠EFG:

Answer:
B. 15 cm
Step-by-step explanation:
Hypotenuse (h) = 17 cm
perpendicular (p) = 8 cm
base (b) = YZ = ?
We know that by using Pythagoras theorem
b = √ (h² - p²)
= √ ( 17² - 8²)
= √225
= 15 cm
YZ = 15 cm
