Angle BCA = 180 - 100
angle BCA = 80
Isosceles triangle ABC has two congruent angles, A and B
2x + 80 = 180
2x = 100
Angles A and B = 50 or y and z = 50
I think lines AB and DE are supposed to be parallel, so angles y and x are consecutive interior angles (supplementary)
x = 180 - 50 = 130
Answer:
Charles completed the quiz problems at the slowest rate
Step-by-step explanation:
we know that
To find out the unit rate divide the number of quiz problems by the time employed
1) Maya completed 15 quiz problems in 10 minutes
so
2) Andrew completed 12 quiz problems in 8 minutes
so
3) Charles completed 16 quiz problems in 16 minutes
so
Compare the unit rates
1 < 1.5
therefore
Charles completed the quiz problems at the slowest rate
Answer:
160
Step-by-step explanation:
With the problem, it's best to put this into a fraction
8/20 of every student will be absent from school less than five days a year, which can then be simplified to 2/5.
There are multiple ways to go about this problem, but my preferred way is to then take 1/5th of 400, which can be done by taking 1*400/5 which equals 80. Since we are asking for 2/5's, just multiply that number by 2, which gives us 160 students.
Answer: 0-o uhhhh 0-o
uhhhh0-o
Step-by-step explanation:
We are actually given here a right triangle where EC is
the hypotenuse. The length of one side is AE = 24, and the other side AC is
simply twice BC, so AC = 7:
EC^2 = AE^2 + AC^2
EC^2 = 24^2 + 7^2
EC = 25
