This is false... you can get an easy example: (-2) + (10) = 10 - 2 = 8
Answer:
m<Q = 133°
Step-by-step explanation:
From the question given above, the following data were obtained:
m<P = (x + 13)°
m<Q = (10x + 13)°
m<R = (2x – 2)°
m<Q =?
Next, we shall determine the value of x. This can be obtained as follow:
m<P + m<Q + m<R = 180 (sum of angles in a triangle)
(x + 13)° + (10x + 13)° + (2x – 2)° = 180
x + 13 + 10x + 13 + 2x – 2 = 180
x + 10x + 2x + 13 + 13 – 2 = 180
13x + 24 = 180
Collect like terms
13x = 180 – 24
13x = 156
Divide both side by 13
x = 156 / 13
x = 12
Finally, we shall determine m<Q. This can be obtained as follow:
m<Q = (10x + 13)°
x = 12
m<Q = 10(12) + 13
m<Q = 120 + 13
m<Q = 133°
2000 divided by 5 is 400. 400 time 3 is 1200. You could also do 2000*.6 (because .6 = 3/5)
Answer:
i think its b
Step-by-step explanation:
im so sorry if im wrong
It looks like the length of a and b should be the same. You can use the Pythagorean theorem (only works with right triangles):
a² + b² = c² (c is the hypotenuse or the longest side of the triangle, a and b are the other side lengths of the triangle)
a² + (4)² = (5)²
a² + 16 = 25
a² = 9
a = 3
a and b have a length of 3
