So you would write out the equation 3(30/25) x 4(12+15) and then do 30/25= 1.2 then do 1.2*3= 3.6 save that answer for later then do 12+15=27 then do 27*4= 108 then multiply together the 108* 3.6= 388.8

I dont have time to do all of these right now my apolgies but Ill explain how to do it.

The 3 angles of a triangle add up to 180.

So let me show you how to do 1.
.

.

1. 58 degrees

92, 30, ?

If we add together the first two angles,
92+30= 122
Knowing the total addition of all three angles would ne 180, we can subtract 122 from it to get the third angle.
180-122= 58

So we now know the last angle is 58 degrees because

92+30+58=180
