Step-by-step explanation:
SA=2*(12*6+12*4+6*4)
SA=2*(72+48+24)
SA=2*144
SA=288
Answer:
55°
Step-by-step explanation:
if an angle is bisected, it get divided into two equal angles .
so, each resulting angle will be half of the angle which is bisected.
hence, measure of each angle formed is
110° / 2 = 55°
im pretty sure the answer is 18
Answer:
Step-by-step explanation:
<u>Use the law of cosines:</u>
- cos C = (25² + 27² - 28²)/(2*25*27)
- cos C = 0.4222
- m∠C = arccos 0.4222
- m∠C = 65°
