If you combine like terrms its easy, you just have to -5+5+6y, 6y=16 y=2.66666667
First find the area of the circle then divide it by 4
Answer:
1 : 5 2 : 10 3 : 15 4 : 20 5 : 25
Step-by-step explanation:
Answer:
19°
Step-by-step explanation:
I have attached an image showing this elevation.
From the image, let's first find the angle A by using cosine rule.
Thus;
8.1² = 5.5² + 13.1² - 2(5.5 × 13.1)cos A
65.61 = 30.25 + 171.61 - 144.1cos A
144.1cos A = 171.61 + 30.25 - 65.61
144.1cosA = 136.25
cosA = 136.25/144.1
cosA = 0.9455
A = cos^(-1) 0.9455
A = 19°
