Answer:
X= 19.9
Step-by-step explanation:
SOH CAH TOA
x is hypotenuse
Opposite is 15
Opposite & hypotenuse - sin
Sin(49) = o/h
Sin(49) = 15/h
xh
Sin(49) x h = 15
÷Sin(49)
h = 15 ÷ Sin(49)
h=19.8751949

Answer:
y = 14
Step-by-step explanation:
Since AC = BC then the triangle is isosceles and the base angles are congruent, that is
∠A = ∠B = 50°, thus
∠C = 180 - (50 + 50) ← sum of angles in Δ = 180°
= 180 - 100 = 80°, hence
5y + 10 = 80 ( subtract 10 from both sides )
5y = 70 ( divide both sides by 5 )
y = 14
PEMDAS. parenthesis, exponents, multiple or divide (whichever come first from left to right), add or subtract (whichever comes first from left to right)
So first do stuff in parenthesis.
Then do divide because thats next on the list and it happens earlier than the multiply one.
So, A
