Answer:
see explanation
Step-by-step explanation:
(8x - 75) and (5x) are vertically opposite angles and are congruent , then
8x - 75 = 5x ( subtract 5x from both sides )
3x - 75 = 0 ( add 75 to both sides )
3x = 75 ( divide both sides by 3 )
x = 25
Then
5x = 5(25) = 125°
8x - 75 = 8(25) - 75 = 200 - 75 = 125°
Answer:12, 84 and 84
Step-by-step explanation:
since we know 3 angles of a triangle = 180 degrees
1 angle = 12 degrees
12 + x + x = 180
12 + 2x = 180
2x= 180 - 12
2x = 168
x = 168/2
x = 84 degrees

That literally makes no sense huh
The area of a pyramid is the sum of area of the base and the area of slant triangles.
The area of the base is 1.5 × 1.5 = 2.25 cm²
The slant height of each triangle, s is 3 cm
The area of the triangles = 1/2 × 1.5 × 3 × 4
= 9 cm²
Therefore, the area of the pyramid
=9 +2.25
= 11.25 cm²
Answer:
P(nickel or dime) = 3/4
Step-by-step explanation:
First, find the total amount of coins that there are:
6 + 14 + 16 + 4 = (20) + (20) = 40
You are trying to find P(nickel or dime). Note that there are 14 nickels, and 16 dimes. Add these two numbers together:
P(Nickel or dime) = (14 + 16)/40
P(Nickel or dime) = (30)/40
Simplify. Divide common factors from both the numerator & denominator (10)
P(Nickel or dime) = (30/40)/(10/10) = 3/4
P(nickel or dime) = 3/4
