Answer:
145°
Step-by-step explanation:
x°+70°=(2x-5)°
x°+70°=2x°-5°
70°+5°=2x°-x°
75°=x°
x=75
JKM=(2x-5)°
=(2x75-5)°
=(150-5)°
=145°
Answer:
£ 144
Step-by-step explanation:
the formula would be :
w = n * r
finding the wages for 20 hours at a rate of 7.20 hours can be solved like this:
w = n *r
w = 7.20 * 20
<u>w =£ 144</u>

Answer: 9/41</h3>
==========================================================
Explanation:
We have a triangle with these three sides.
Use the pythagorean theorem to find b
a^2+b^2 = c^2
b = sqrt(c^2 - a^2)
b = sqrt(82^2 - 80^2)
b = sqrt(324)
b = 18
This is the missing vertical leg of the triangle. And this is also the side opposite angle C.
We have enough information to compute the sine of the angle.
sin(angle) = opposite/hypotenuse
sin(C) = AB/AC
sin(C) = 18/82
sin(C) = (9*2)/(41*2)
sin(C) = 9/41
