Multiply 4(-5) then add 6 and theres your X
Answer:
90°-x°=180°[by linear pair]
x=180°-90°
x=90°
angle cbd=45°
45°- (x+5)°=90°
x+5=90-45
x+5=45
x=45-5
x=40
angle abc
x+5
40+5
45°
Answer:

Step-by-step explanation:
To solve an equation for one of its variables do that:
- Underline the variable
- Separate it one side and the other terms on the other side
- Make its coefficient equal to 1
Let us use these steps to solve our question
∵ V = πr²h
→ Underline r²
∴ V = π<u>r²</u>h
→ Take π and h to the other side by dividing both sides by πh
∵ 
∴ 
→ The coefficient of r² is 1, so switch the two sides
∴ 
thy get 55/75 and you want to know x/300
55/75 x X/300
cross multiply 55 x 300 = 16500
divide that by 75
16500/75 = 220
x = 220
they will get $220
