ANSWER


EXPLANATION
The given triangle has a right angle.
The side opposite to the 45° angle is 7 units.
To find angle x, we use the tangent ratio.
Recall the mnemonics TOA, which means,




To find y, we use the sine ratio, which means






The answer is C 102 degrees. It is so because a triangles 3 angles add up to 180 degrees. If you know 2 of your angles, you would add them together and subtract that by 180 to find your last angle.
Answer:
BCD is the outer angle of triangle ABC
=> BCD = ABC + BAC
<=> 150⁰ = ABC + 118⁰
=> ABC = 150⁰ - 118⁰
<=> ABC = 32⁰
Answer:
480
Step-by-step explanation:
(16x10x8) divided by 2 = 480
