Answer:
x = 7.5
Step-by-step explanation:
Since the midsegment and the third segment of the triangle are parallel to each other, therefore,
Cross multiply
Subtract 24 from each side
54 - 24 = 4x
30 = 4x
Divide both sides by 4
30/4 = x
7.5 = x
x = 7.5
Answer:
-33 or 33
Step-by-step explanation:
The seventh term of an AP is written as:
The eleventh term of an AP is written as:
If the 7th term is 11 times the 11th term, then;
Expand to get:
We must have a=-52 and d=5
Or
a=52 and d=-5
For the first case, the 18th term is :
For the second case,
Answer:
4.
Once is opposite to
, they are the same. It is the same for
, equals to 40º.
m∠y = 40º
The ∠x and 40º are supplementary, therefore ∠x = 140º.
∠z = 140º
m∠x = 140º
m∠y = 40º
m∠z = 140º
5.
Considering the explanation from the question 4:
m∠x = 50º
m∠y = 130º
m∠z = 50º
