Answer:
Question 8: 8.94
Question 9: 8.94
Step-by-step explanation:
Question 8: Using pythagorean theorem [a^2+b^2=c^2], we do (8*8)+(4*4) getting 80 which is our c^2. Now we find the square root of which is 8.94.
Question 9: Using pythagorean theorem [a^2+b^2=c^2], we do (5.3*5.3)+(7.2*7.2) getting 79.93 which is our c^2. Now we find the square root of which is 8.94.
Please correct or msg me if this is wrong.

Answer:
Step-by-step explanation:
<h3>Q13</h3>
The greater the angle the greater the opposite side
<u>Sides in ascending order:</u>
- AB = 17, AC = 18, BC = 21
<u>Angles in same order</u>
<h3>Q14</h3>
<u>As above, sides in ascending order:</u>
- AB = 15, AC = 16, BC = 17
<u>Angles in same order</u>
<h3>Q15</h3>
<u>Exterior angle equals to sum of non-adjacent interior angles</u>
- 142° = x + 66°
- x = 142° - 66°
- x = 76°
<h3>Q16</h3>
<u>Same subject and isosceles triangle:</u>
- x + x = 158°
- 2x = 158°
- x = 79°
<h3>Q17</h3>
<u>Same subject</u>
- m∠QSR = m∠QPS + m∠PQS
- 2x = x + m∠PQS
- m∠PQS = 2x - x
- m∠PQS = x
ΔPQS has two angles with the measure of x, hence their opposite sides are congruent and the triangle is isosceles
Depends what your talking about but the easy way is 40 and 90
