You would want to use the midpoint because they are perpendicular so it will have four right angles. find the midpoint of GH and then place F where it should be and make E equal to that

Answer:

18.0 cm to 1 decimal point.

Step-by-step explanation:

First work out the unknown side (s) of the right triangle using the Pythagoras theorem:

s^2 = 13^2 - 5^2

= 169 - 25 = 144

s = sqrt 144 = 12 cm.

Now consider the other triangle:

s = 12

The missing angle = 180 - 65 - 40 = 75 degrees.

By the Sine Rule:

x / sin 75 = 12 / sin40

x = 12 sin 75 / sin 40

= 18.03

if R+M=90
and you know the values of both of them you will simply substitute them with their values and answer the question in the form of an equation as shown in the photo
