Answer:

The given  triangle is an acute angled triangle.

Step-by-step explanation:

Acute Angle:  The angle whose measure is less than a right angle 90 degrees, such an angle is called an acute angle.

Now, here ∠1 = 58°  ,  ∠2 = 50° and  ∠3 = 72°

As each of the angle is less than 90° .

⇒ Each angle is an acute angle.

So, the given  triangle is an acute angled triangle.

In ΔEFG, the measure of ∠G=90°, the measure of ∠E=20°, and GE = 75 feet. Find the length of EF to the nearest tenth of a foot.
LenKa [72]

Answer:80 feet

Step-by-step explanation:

Sum of < in a triangle is 180°

<G + <E + <F=180°

90 + 20 + < F = 110

< F = 70°

Using sine rule

sin G\EF = sin F\EG

sin90°\EF = sin70°\75

EF = 75sin90°\sin70°

= 79.81

=80 to the nearest tenth feet.

56 students signed up for the school play. About 34% of these students were boys. At the auditions only 31 girls attended. What
Elza [17]

56 students represents 100 % and

X boys represent 34%,

so x= 56•34/100= 19.04 so approximately 19 boys

56-19= 37 girls signed up.

Now 37 girls represent 100% and 31 girls represent x % ,

So x= 31•100/37= 83.78% about 84% of the girls attended
