Answer:
w = 11
Step-by-step explanation:
<u>Step 1: Subtract 4 from both sides</u>
15 = w + 4
15 - 4 = w + 4 - 4
11 = w
Answer: w = 11
Answer:
∠ 5 = 151°
Step-by-step explanation:
A linear pair are supplementary, that is sum to 180°
∠ 5 = 5 ∠ 6 + 6 , thus
∠ 5 + ∠ 6 = 180, that is
5 ∠ 6 + 6 + ∠ 6 = 180
6∠ 6 + 6 = 180 ( subtract 6 from both sides )
6 ∠ 6 = 174 ( divide both sides by 6 )
∠ 6 = 29°
Thus
∠ 5 = 180° - 29° = 151°
Sine = opposite / hypotenuse
cosine = adjacent / hypotenuse
So, in a right triangle which has the opposite side equal to the adjacent side, we will have the sin (theta) = cosine (theta)
This would be an isosceles right triangle which is also called a 45 45 90 triangle.
sine (45) = 0.70711 and the
cosine (45) = 0.70711
