Answer:

Step-by-step explanation:
Given
- 
The LCM of 4 and 5 is 20
= 
= 
Your answer is B) -5/6.
We can find this using the formula (y2 - y1)/(x2 - x1) and substitute in the coordinates:
(-2 - 3)/(5 - -1) = -5/6
I hope this helps!
150 x 2, so easy, its 300 dude give brainliest, jk i dont need brainliest its too easy, but here you go
Answer:
y is 150
Step-by-step explanation:
a straight angle always measures 180 degrees. if x is 30, the simply minus 30 from 180. that should give u 150 which is your answer.
hope this helped!
Answer:
see explanation
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
=
( cross- multiply )
9x = 72 ⇒ x = 8
Also
=
( cross- multiply )
6a = 45 ⇒ a = 7.5
And
=
( cross- multiply )
6b = 63 ⇒ b = 10.5
Corresponding angles in the 2 figures are congruent, thus
∠s = 83°
Each lower base angle is supplementary to the upper base angle on the same side, hence
∠r = 180° - 30° = 150°
