Question 20 not yet answered marked out of 1.00 not flaggedflag question question text luna created a trash can in the shape of a triangular prism. the sides of the triangle are 1.6 feet, 2.3 feet, and 1.2 feet. find the measures of the angles of the triangle to the nearest tenth.

Consider the triangle with sides a=1.6, b=2.3 and c=1.2 feet. You can use cosine theorem twice to find two unknown angles:

1.

Then you can conclude that ∠B is obtuse (because ) and m∠B=110°.

2.

.

Then you can conclude that ∠C is acute (because ) and m∠C=29°.

3. m∠A+m∠B+m∠C=180°, then m∠A=180°-110°-29°=41°.

m∠A=41° (∠A is opposite to the side a=1.6), m∠B=110° (∠B is opposite to the side b=2.3) and m∠C=29° (∠C is opposite to the side c=1.2)

21.4 i did it already for s1

step-by-step explanation:

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
