Answer:
1. m∠8 = 30° 2. m∠5 = 27° 3. m∠1=m∠8 4. m∠3=m∠7
m∠6 = 180-120
m∠6 = 60
if m∠1 is 120 and m∠6 is 60, it is true because m∠2 and m∠1 are linear pairs/supplementary, so when you set them = 180 and solve for m∠2, you'll get 60. and because corresponding angles are equal and angle 6 and 2 corresponds, m∠6 will be the same measure as m∠2
Step-by-step explanation:
- because corresponding angles are equal in measure.
- because alternate interior angles are equal in measure
- because they alternate
- because they correspond
- because co-interior angles are supplementary, subtract 120 from 180 to get m∠6.
The answer is D , start from 2 and count to 8 and it gives you your answer
Answer:
Below in bold.
Step-by-step explanation:
A). 9.9^2 is close to 10^2 = 100
Round 1.79 to 1.8
So an estimate is 1.8 * 100
= 180.
B). √97.5 / 1.96
( I am assuming that the square root is of 97.5 only).
is approximately equal to √100 / 2
= 10/2
= 5.
Angle e will be 132 because it is a vertical angle with 132, and they are congruent. Angle d will be 48 because it must add up to 180, and 180-132=48. Angle c will be 42 because that and 138 are supplementary angles, and they need to add up to 180, so 180-138=42. Angle b will be 90 because it is across from the 90 degree angle, and so they are congruent. And angle a will be 90 as well because angles a and b are supplementary angles, so they need to add up to be 180 degrees. I hope that helps! :)
