The size of the 4th angle is 72.
Given:
1st angle = 148
2nd angle = 104
3rd angle = 36
shape = quadrilateral.
A quadrilateral is a shape that has 4 sides or edges, 4 corners or vertices.
It goes to show that it must also have 4 angles. These four angles must give the sum of 360°.
Since the first three angles are given, we can get the fourth angle by deducting the sum of the three angles from 360°
4th angle = 360° - 148° - 104° - 36°
= 360° - 288°
4th angle = 72°
Step-by-step explanation:
1. 6(9+3)=57
2. 3(12+6)+2(4)=29
3. 5(3-16)=65
(3×4+12(4)=48
Answer: 1.17
Step-by-step explanation: multiply 9 x 0.13
Pretty sure you just divide 14,136/23,550 and then that percent would be the answer
