Consider the right triangle in the attached diagram. Using the Pythagorean theorem, you can find the distance marked "a" by
r² = a² + o²
a = √(r² - o²) = √(20² -16²)
a = √(400 - 256) = √144 = 12
The
maximum depth is the difference between r and a, so is (20-12) cm =
8 cm.
Answer – 30
Solving for 11 + 5 + 3 x 2 + 8 x 1
Using the Order of Operations – BODMAS
Multiplication is prioritized above addition
Therefore, 11 + 5 + 3 x 2 + 8 x 1
= 11 + 5 + (3 x 2) + (8 x 1)
= 11 + 5 + 6 + 8
= 30

Answer:
The measures of the angles are 50° and 130°
Step-by-step explanation:
Let
x ----> the measure of one angle
y ----> the measure of the other angle
we know that
If two angles form a linear pair , then their sum is equal to 180 degrees
-----> equation A
----> equation B
substitute equation B in equation A
solve for y
Find the value of x
The measures of the angles are 50° and 130°
The correct answer would be D !m
A( reduction
I don't know how to do B
