Answer:
y = 1, 1.319, 1.024, 0
Step-by-step explanation:
Given equation:
Answer:
1 = 39 degrees (some theorem, like triangles sharing a bisector or something sorry)
3 = 51 degrees (if 1=39 and 2=90 degrees since its on a right angle, and a triangle's angles add up to 180, then you subtract 1 and 2 from 180 and get 51
3/4=x/60 so you divide 60 by 4 and get 15x3=45/60
Step-by-step explanation:
Equation:
First step:
Second step:
Third step:
Fourth step:
Answer:
100°
Step-by-step explanation:
Total angle in a triangle is 180
∠C = 180 - 20 - 60
= 180 - 80
= 100
