U can find the angle by adding 90 degrees and 75 degrees which equals 165 degrees. with this, you can do the equation 180-165 which equals 15. 15 is the answer for the missing degree. all angles in a triangle must equal 180 degrees when u add them together. for the angle on the right, same thing. 90+80 which equals to 170. so 10 is the degree for the angle on the right.
Answer:
V= 175 centimeters cubed
V= 126 inches cubed
Step-by-step explanation:
<u>1st question:</u>
V1=2×5×5= 50cm cubed
V2=2×5×5= 50cm cubed
V3= 5×3×5= 75cm cubed
V= 175 centimeters cubed
<u>2nd question:</u>
V1=3×3×2= 18in cubed
V2= 2×3×2= 12in cubed
V3= 6×8×2= 96in cubed
V= 18+12+96
V= 126 inches cubed
I think its fqalse sure thio
3a^5 - (-a^5) = 3a^5 + a^5 = 4a^5
6a^7 - 2a^7 = 4a^7
-3a^5 - (-2a^5) = -3a^5 + 2a^5 = -a^5
7a^7 - 8a^7 = -a^7
