The common factors for 20 is 1,5
25 is 1,5
40 is 1,5
GCF:5
Question 1:
This question may look complicated, but we have some unnecessary info.
All we need to know that the angle next to y must also be 30 degrees because of alternate interior angles.
Thus, y + 30 = 180
Subtract both sides by 30
y = 150
Question 2:
Angle a must also be 36 because of alternate interior angles.
We also have a triangle.
We know that 36+77+?=139 because of alternate interior angles.
Let's find the ? angle.
? = 26
Now we know that a+b+?=180 because it's a triangle.
36+b+26=180
b=118
That's all we need. The last choice is the only answer that matches these two answers.
(If you want to find the value of c by solving for it, just see that there's a triangle where all the angles but c is known)
Have an awesome day! :)
Answer:
$140
Step-by-step explanation:
if 30% of full price = $42 then 100% = 42/0.3 = 140
130 would be the correct answer
Answer:
No
Step-by-step explanation:
The triangles are not similar since triangle B has an angle (18 cm) that does not correspond to 10, unlike the other angles which you can get by multiplying 3/2.
