We may draw a vertical that bisects the vertex angle and the shorter side of the triangle, to form a right-triangle with the measurements:
hypotenuse = 8
length = 1.5
We may then apply:
sin(∅) = P / H
sin(∅) = 1.5 / 8
∅ = 10.8 ≈ 11°
This is half of the vertex angle, so the vertex angle is:
11 * 2 = 22°
Answer:
1/3
Step-by-step explanation:
5 over 15
divide both by 5 to simplify 1 over 3
Alex = 6x
Peter = x
6x = x + 50
5x = 50
x = 10
Alex = £60
Peter = £10
together = £70
Answer:
-12x^2+46x-6
Step-by-step explanation:
combine like tens and subtract then from eachother
Sum of interior angles in a pentagon=540°
148+112+2x+2x+10+90=540
360+4x=540
4x=540-360
4x=180
x=180/4
x=45°
