Frank is x years old Millie is 12 years younger than frank three times Millie age is equal 132

168 years

Step-by-step explanation:

Millie's age= Frank's age - 12 × 3 = 132 years

Let Frank's age be x

Millie's age = x - 36 = 132

x = 132 + 36

x = 168 years

Frank is 168 years

Step-by-step explanation:

Let the age if Frank be x

while the age of Millie is 12 times 3 younger than Frank = 132

12×3younger= 36 years younger

to find Franks age represents the scenario with the equation x-(12×3)=132

x-36=32

x=132+36

x=168 years

step-by-step explanation:

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
