Answer:
y = 100°
Step-by-step explanation:
x = 40° (vertical angles are congruent)
y is an exterior angel of a triangle that has two opposite internal angles, x (40°) and 60°.
According to the exterior angle of a triangle, thus:
y = 40 + 60
y = 100°

Answer:what do u need help with?
Step-by-step explanation:
The concept useful in finding the answer to this item is ratio and proportion, the ratio of the height of your friend with the shadow casted should be proportional to the height of the rock with the length of the shadow it cast. That is,
5.5 ft / 18 ft = x ft/ 209.5 ft
The value of x from the equation above is 64 ft.
Answer:
z=13
Step-by-step explanation:
Ok we are to solve for z from the given equation
2z=26
It's like making z the subject of formula
We will be able to think fast on how to make z the subject of formula from the equation
To make z the subject of formula we will have to divide both sides by 2
z=13
Therefore the value of z is 13
To solve this kind of question you must be to think on ways to eliminate the number behind the required number
Hope you understand
