Answer:

Mark me brainliest

Step-by-step explanation:

sum of angle of triangle =180

3)A=70

B=72

C=z

Answer 2

Answer: 4. 1st angle= 90 degree, 2nd angle= 70 degree, 3rd angle= 20 degree

5. angle B= 40 degree

6. z= 38 degree

Step-by-step explanation:

A triangle is always 180 degree

4. The question itself tells the half answer- right angle triangle= one angle is 90 degree, 2nd angle is 70 degree and the 3rd angle is the sum of the two angles subtracted by 180. 90+70-180

                                                     160-180=20

5. Angle B is equal to angle C and angle A= 100 degree. So, a triangle is 180 degree, if one angle is 100 degree the other two will be 180-100

                                                                                                         =80

                                                                                                         =80/2

80/2 because their are two same angles                                   =40

6. One angle is 70 degree other is 72 degree.

Therefore, a triangle is 180 degree

70+72-180

=142-180

=38 degree
