Subtraction and division are from the principal operations of PEMDAS. PEMDAS stands for parentheses, exponents, multiply and divide, add and subtract and thats it! Hope this helps and remember to mark as brainliest!
Step-by-step explanation:
The hypotenuse of a right triangle is always the side opposite the right angle. It is the longest side in a right triangle. The other two sides are called the opposite and adjacent sides.

Answer: ∠P= 20°
<h3>
Step-by-step explanation: Well we know that the sum of a triangle always equals to 180°, so ∠P + 80 +80 = 180°
</h3>
∠P + 160 = 180
Subtract 160 from both sides, 160 on the left is cancelled so that 180-160 equals 20
∠P=20°
4/7 × 3/4
(4 and 4 are cancelled )
7×3
the answer is 21
the marked angles are complementary → B
All 3 triangles are right with one angle = 90°
the sum of the angles in a triangle = 180°
thus the remaining 2 marked angles sum to 90°, thus are complementary
