Answer:
6
Step-by-step explanation:
first we represent the unknowns using variables:
let x = measure of angle 4
let 3x+4 = measure of angle 3 (from the second statement)
then we set-up the equation. since the angles form a linear pair, their sum is equal to 180 degrees. therefore,
x + 3x + 4 = 180
4x + 4 = 180
4x = 176
x = 44 degrees (measure of angle 4)
3x + 4 = 136 degrees (measure of angle 3)
Answer:


Step-by-step explanation:
Given



See attachment for illustration
Solving (a): Trigonometry ratio to calculate h.
From the attachment, we have:

Multiply both sides by d


Rewrite as:

Solving (b): The value of h
We have:


So:



Answer:
True
Step-by-step explanation:
Answer:
The Temperature on Thursday morning will be -13° Fahrenheit.
Step-by-step explanation:
Given:
Temperature on Wednesday evening = -5 Fahrenheit
Temperature decreased Throughout the night = 8 degrees
We need to find the Temperature on Thursday morning.
Now we know that;
The temperature decreased means the temperature went more below the current temperature.
So To calculate Temperature on Thursday morning we will Subtract the temperature which got decreased by the temperature noted on Wednesday evening.
framing in equation form we get;
Temperature on Thursday morning = 
Hence The Temperature on Thursday morning will be -13° Fahrenheit.
