Answer:
1) 180 degrees; straight angle
2) (5x-18)+(4x+45)=108
3) x=17
4) 90 degrees; right angle
5) (3x+6)+(5x+4)=90
6)x=10
Step-by-step explanation:
Answer:
2/3
Step-by-step explanation:
First, you figure out how many marbles are in total, which is the denominator. The total number of marbles is 30.
Then, you figure out how many marbles are blue, which is the numerator. There are 20 blue marbles.
Finally, you simplify the fraction. 20/30=2/3.
You could continued the same way.
∡KHL≅∡PHN= 38° reason cross-angles which are the same
∡MHN≅∡JHK=62° reason cross-angles
The total sum of all angles is 360°
∡JHP≅∡MHL=x reason cross-angles
2x+(2*62)+(2*38)=360 => 2x+124+76=360 => 2x+200=360 =>
2x=360-200=160 => x=160/2=80°
∡JHP≅∡MHL=80°
Good luck!!!
