To find the third angle;
57 + 82 = 139
The total measurement of a triangles angle is 180
180 - 139 = 41
<u>The Third angle is 41</u>
Answer:
3/4
Step-by-step explanation:
pizza is cut into fourths because there are for people eating it. the brothers have 3/4 of the pizza because there are only 3 brothers
You can simply count 0,1,2,3 when zero is your starting point
Memorize Soh Cah Toa, which means:
sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent
opposite & adjacent are determined based on the angle being referenced.
hypotenuse is ALWAYS opposite of the 90 degree angle.
sin Y = 12/13
cos Y = 5/13
tan Y = 12/5
