Answer:
Step-by-step explanation:
123
Answer:
<1 = 112degrees
<2 = 33degrees
Step-by-step explanation:
From the figure, the sum of interior angles of the larger triangle is equal to the exterior, hence;
<1 + 15 = 127
<1 = 127 - 15
<1 = 112degrees
For the smaller triangle;
<1 = <2 + 79
112 = <2 + 79
<2 = 112-79
<2 = 33
Hence the measure of <2 is 33degrees
In a 30-60-90 triangle, if the short leg is x then the longer leg is x√3 and the hypotonuse is 2x
so if the rafter (hyppotnuse) is 9ft then
9ft=2x
4.5ft=1x
the short leg is 4.5ft
