Answer:
x = 36°
Step-by-step explanation:
See attachment
To find the measure of angle a subtract;
360° - 144° - 180° = 36°
To find the measure of angle b subtract;
360° - 72° - 180° = 108°
A triangle equals 180°, so subtract for angle x:
180° - 36° - 108° = 36°
So first we know he walks 2 and 7/10 miles, which is the same as 2.7 miles.
We also know whenever you multiply a number by 10, all you have to do is move the decimal to the right ONE PLACE.
So here you would multiply 2.7 times 10. You move the decimal place right ONE place, so now you have 27.0. Therefore, he walked 27 blocks.
Hope that makes sense! If not feel free to ask any questions in comments! :D
Step-by-step explanation:
Note that the denominators in the expression are perfect squares:
We can then write the given expression as
I would say B.The measures of corresponding angles of ABCD and KLMN are in the ratio 1 : 2, but the lengths of corresponding sides of ABCD and KLMN are not proportional.
