Answer:
right triangle
Step-by-step explanation:
We know that the total angles of the triangle are 180 degrees:
(x) + (4x-10) + (2x+15) = 180
7x - 10 + 15 =180
7x + 5 = 180
7x = 180 - 5
7x = 175
x = 175÷ 5 = 25
Now we calculate each angle
x=25
4x-10= (4*25) -10=100-10=90
2x+15=(2*25)+15=50+15=65
Because we have a right angle, then the triangle is right triangle
The answer is 62^ it reflects angle IK
Answer:
1/3
Step-by-step explanation:
(1/3)^2x(1/3)^-1
so, we can write this as:
1/3 x 1/3 x 3/1
if calculated by cutting, the answer is 1/3
There is also an easier way to do this,
(1/3)^2 x (1/3)^-1
as the bases are same, the powers will be added.
2+(-1)
2-1
=1
so,
(1/3)^1 or 1/3
Answer:
n = r - 2.5
Step-by-step explanation:
The discount Khalid is giving is $2.5 off, so the equation represents the neighbors' price equals the regular price minus 2.5.
Answer:
x ≤ - 27
Step-by-step explanation:
Given
≥ 3
Multiply both sides by - 9, reversing the symbol as a result of multiplying by a negative quantity.
x ≤ - 27
