Answer:
A
Step-by-step explanation:
RT=12
TU=5
RU=12+5=17
RS=17+7=24
SU=√(RS²-RU²)=√(24²-17²)=√(24-17)(24+17)=√(7×41)=√287
area=1/2×12×√287=6×√287≈101.6 unit²
Answer:
1 is correct
Step-by-step explanation:
3(4x + 5) = 12
12x + 15 = 12
12x = -3
R=R/100=4/100=0.04 per year. Solving equation A=P(1+rt ). A=4000(1+0.04)=4160. A=$4160
Answer:
135°
Step-by-step explanation:
formula = (n-2) * 180, whereby 'n' is the number of sides.
therefore, (8-2) * 180 = 1080°
1080° ÷ number of sides
= 1080° ÷ 8
= 135°
It is an open circle on 2 and then pointing to the left
