−18x−40
9x square minus 18x minus 40
I think you basically just got to add everything up . I mean , i can already tell this is a graph question but it says perimeter so perimeter somehow means add everything up. But im still not too sure ..
60/15=4 meaning 25% of the dogs are purebreed
Answer: G = 50°, I = 50°, H = 80°
Step-by-step explanation:
First and foremos, the sum of three angles of a triangle is 180°
2x + 2x + (4x - 20) = 180°
8x - 20 = 180°
8x = 180° + 20 (adding 20 on both sides)
8x = 200°
x = 200/8
x = 25
The value of the angles can be found by replacing the value of x with 25
2x = 2 x 25 = 50°
Therefore, the angle of two angles are 50°
And the other is (4 x 25) -20 = 80°
Answer:
26m
Step-by-step explanation:
The value of the opposite side (height of the flagpole) is to be determined given the angle and the value of the adjacent side(horizontal distance )
We would use tan 18 to determine the value of the missing side
tan 18 = opposite / adjacent
0.3249 = opposite / 80
0.3249 x 80 = 26m
