The value of a is 70° and b is 20°
Angle θ between two vectors is given by,

; where

;

and

.
Therefore,
Let us say that h is the height of the guardrail.
Therefore the inequality equation that we can generate from this scenario is:
| h – 106 | = ± 7
There are two ways to solve this, either the equation is
positive or negative.
When the equation is positive, therefore:
| h – 106 | = 7
h = 7 + 106 = 113 cm
When the equation is negative, therefore:
| h – 106 | = - 7
h = -7 + 106 = 99 cm
So the height must be 99 cm to 113 cm
Answer: Hello there!!! the answer is - 91
Step-by-step explanation:
Step 1: convert all of the variables in the equation into numbers.
The equation will look like this - 8^2 + 3^3
Step 2: solve 8^2 and 3^3
8^2 = 64 and 3^3 = 27
Step 3: solve the equation sooooo the equation will now look like this
64 + 27 which is 91
PLEASE MARK ME BRAINLIEST I WOULD HIGHLY APPRECIATE IT!!!!!!
