Answer:
168). C
169). C
170). C
Step-by-step explanation:
For the first angle, it is a right angle, so it measures 90 degrees.
x and 50 are complementary angles, meaning they add up to 90 degrees.
So, subtract 50 from 90 to get 40, which is equal to x.
45 and x are supplementary angles, meaning they add up to 180 degrees.
Subtract 45 from 180 to get 35 degrees, which is the measure of angle x.
All angles in a triangle add up to 180 degrees.
So, 70 + 56 = 126, 180 - 126 = 54.
Since the unknown angle is x - 5, 54 + 5 = 59, which the the measure of angle x - 5.
Which type of question is this
Answer : option A
16<=2(3x-1) and 2(3x-1)<28
Phyllis solved the compound inequality. She began by first breaking the inequality into two separate inequalities. Then she correctly solved each for x
3<=x and x<5
x>=3 and x<5
Now we graph the solution
x>=3, we have = sign so we use closed circle at 3.
Then for greater than symbol we shade to the right
For x<5, there is no = sign so we use open circle at 5
for < than symbol we shade to the left
For x>=3 and x<5, we take the intersection of both graphs
So option A is the answer.
