If you add up all the angles in a triangle it will always be 180.
180 - 45x is angle TRS
Therefore 180 - 45x + 25x + 57 + x = 180
Subtract 180 from both sides
-45x + 25x + 57 + x = 0
Subtract 57 frok both sides
-45x + 25x + x = -57
Combine like terms
-19x = -57
divide both sides by -19 and you get
x = 3

The sum of the angles in a triangle is 180°. It means that when you add up the three angles, you would get 180°.

The angle on a straight line, is also 180°.

Since ∠QRT = 45x, then...

∠TRS = 180° - 45x

So now you add up the angles in the triangle:

(180° - 45x) + 25x + (57 + x) = 180°

Combine like terms:

-19x + 237° = 180°

Subtract 237° to both sides:

-19x = -57

Now, divide both sides by -19:

x = 3

Which of these choices show a pair of equivalent expressions?
NISA [10]

Answer:

A. 6^2/7 and (√6)^7

Step-by-step explanation:

Because we can't get 6 out of root as a whole we need to use the power to show its value when we do so.

The power of (√6)^7 has is seven and degree of the root is 2 so we have to put 2/7 over 6 when we take it out of root.

For the given equation find the value a, b, and c, determine the direction in which the parabola opens and determine the y-inter
Y_Kistochka [10]

Answer: Table A

Step-by-step explanation:

The coefficient of x^2 is 1, the coefficient of x is -6, and the constant is 0. This means that a = 1, b = -6, and c = 0.

  • This eliminates tables B and C.

Now, we need to determine if the graph opens up or down to differentiate between A and B. Since the coefficient of x^2 is positive, the graph opens up.

  • Thus the answer is <u>Table A.</u>

1. Set up the following word problem as an equation and solve. Then write your answer as a complete sentence.
klasskru [66]
<span>a/b = 3/5 ----- a = (3b)/5
a + b = 136 --- (3b)/5 + b = 136
3b + 5b = 680
8b = 680
b = 85
a = (3b)/5 = (3 * 85)/5 = 51

a = 85 and b = 51</span>

Why wuld 8/4 be considerd a whole number
kumpel [21]

Answer:

because 8/4=2

Step-by-step explanation:

4/4=1

8/4=2

it's because the numerator is bigger if it were 6/4 it would be a mixed number but the eight goes in to 4 directly 2 time so therefore it's 2.
