Answer:
Two right angles = 180 degrees
Step-by-step explanation:
A right angle = 90 degrees
The sum of the interior angles of a triangle = 180 degrees
Two right angles (2 * 90) = 180
180 = 180
Therefore, the sum of the interior angles of any triangle is equal to two right angles.
Answer:
The answer would be 80 ° because 5×( 2 + 13 or x +1 ) is 80
Step-by-step explanation:
ABD is 80°
If DEB is 42 °
∠ ABD = 5(2X+1)
∠ DBC = 3X+6
∠ EBC = Y +135/2
∠ ABD and ∠ DBC are linear pairs
∴ ∠ ABD +∠ DBC = 180
∴ 5(2X+1) + 3X+6 =180
solve for x
∴ x = 13
∴∠ ABD = 5(2X+1) = 5(2*13+1) = 135
∠ DBC = 3x+6 = 3*13+6 = 45
∠ ABD and ∠ EBC are vertical angles
∴ ∠ ABD = ∠ EBC = 135
∴ y +135/2 = 135
∴ y = 135/2
Answer:
x=-20/9
Step-by-step explanation:
4(4x+1)=3x-4(6-x) +8
16x+4=3x-24+4x+8
16x-3x-4x=8-4-24
9x=-20
x=-20/9
A and C are the only ones who could work...
Because 16+16=32 2+2=4 so 4 counselors to 32 campers
16+16+16=48 and 2+2+2=6 so 48 campers to 6 counselors could also work.
Answer:
<h2>
(f - g)(x) = 3x^2 - x - 2</h2>
Step-by-step explanation:
Here we subtract g(x)=x+2 from f(x)=3x^2-4
Properly labeled, we get:
(f - g)(x) = 3x^2-4 - (x+2) (Use of parentheses is essential here.)
or
(f - g)(x) = 3x^2 - x - 2
