The answer is positive final answer
Answer: a = 122*
The three angles added together form a circle or 360*.
Set a + b + c = 360 and solve for a
a + 66 + 172 = 360
Subtract 238 from both sides to get a
a = 122*
Because the surface area is of a 2-D SHAPE to find a area of a 2-D shape is l x w
Answer:
3
Step-by-step explanation:
add 8 to both sides then x=3
Answer:
US is parallel to RT, and UR is parallel to ST
ST is perpendicular to US and UR is perpendicular to RT
Basically anywhere that there's lines that make right angles are perpendicular to each other
