Answer:

m∠1 = 20°

m∠4 = 110°

Step-by-step explanation:

m∠1 + 70° = 90°

m∠1  = 20°

70° + m∠4 = 180°

m∠4 = 110°

Answer:

\boxed{m  \angle1 \: = 20} \\ \\ \boxed{m \angle4 = 110}

Step-by-step explanation:

m  \angle1 \: =90 - 70 = 20 \\   m \angle4 = 360 -( 180 + (180 - 110)) \\ m \angle4 = 360 - 250 \\ m \angle4 = 110

5 men take 45hours to build a wall.how long will it take 9men working at the same wall?​
Karolina [17]

Answer:

<u>25 hours</u>

Step-by-step explanation:

It takes 5 men 45 hours to build a wall.

So, if no. of men increases by 1.8 [∴ 5 x 1.8 = 9],

then time taken reduces by that same amount.

=> 45 hours / 1.8

=> 45 / (9/5)

=> 45 x 5 / 9

=> 5 x 5

=> <u>25 hours</u>
