@SanjanaP please help someone

OpenStudy (sanjanap):

It's the sort of the same as the last one.

OpenStudy (sanjanap):

180-(60+50)= ?

OpenStudy (just_one_last_goodbye):

ok 50 + 60 is 110

OpenStudy (sanjanap):

180-110 = 70 right?

OpenStudy (just_one_last_goodbye):

180 - 110 = 70

OpenStudy (just_one_last_goodbye):

yes

OpenStudy (sanjanap):

since vertical angles....2x=70 x=35

OpenStudy (just_one_last_goodbye):

THANKS SO MUCH!!!

OpenStudy (anonymous):

2x = 180 - (60 + 58) 2x = 180 - 118 2x = 62 x = 31 The angle left in that triangle was vertical to 2x.

OpenStudy (just_one_last_goodbye):

OpenStudy (just_one_last_goodbye):

Use three or more sentence to explain why every equilateral triangle must also be an acute triangle.

OpenStudy (anonymous):

if an equilateral triangle has 3 equal sides, then it should have 3 equal angles. However the sum of each 3 equal angles should be 180. so it measurement of each 3 angles should be 60. since the measure of all the 3 angles are 60 (which is acute as POsitrOn said), the triangle is said to be acute.
