Someone please help and hurry

For number 1, the answer is 90°, 55°, and 35°

Step-by-step explanation:

A triangle always equals 180 so you have to subtract the other angles to find the third one. Since you already know that one angle is 35° and the other is 90° you can do 180-90-35 and that equals 55 so those three are your three angle measures

For the show your work part of #1 write:

180°-90°-35°=55°

measurement of the swimming pool is given as = 7 yards 4.79 feet

first we will convert this to yards only.

1 foot = 0.33 yards

so, 4.79 feet = yards

so total yards are = yards

now we will convert this in meters.

1 yard = 0.914 meters

8.580 yards = meters

0.842 m = 0.842*100 = 84.2 cm

this becomes 7 meters and 84.2 cm

hence, the pool is 7 meters and 84.2 cm wide.
