The ratio of the angle measures of a triangle are 3: 3: 4. what are the angle measures and the triangle's classification? 54°, 54°, and 72°; equilateral triangle 54°, 54°, and 72°; acute triangle 36°, 36°, and 108°; scalene triangle 36°, 36°, and 108°; obtuse triangle

B

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

sum the parts of the ratio 3 + 3 + 4 = 10 parts

divide 180° by 10 to find one part of the ratio

= 18° ← 1 part of the ratio

3 parts = 3 × 18° = 54°

4 parts = 4 × 18° = 72°

thus the 3 angles are 54°, 54° and 72°

All 3 angles are acute angles

Hence an acute angled triangle

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
