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
Answer:
The measure of Angle G is 62.5°.
Step-by-step explanation:
Given:
Δ EFG is an Isosceles Triangle.
EG = EF
m∠ E = 55°
To Find:
m∠ G = ?
Solution:
Δ EFG is an Isosceles Triangle. ........Given
EG = EF ..............Given
∠ G = ∠ F = x (say) ..................Isosceles triangle property
Now in Δ EFG we have
∠ E + ∠ G + ∠ F = 180° .......... Angle sum property of triangle
On substituting the values we get
The measure of Angle G is 62.5°.
Answer:
Step-by-step explanation:
Hmmmmm you did not give the full equation for the original line.
However, parallel lines have identical slopes. Whatever coefficient (m) is associated with the x value, will be the slope of the parallel line when the equation is put in the form
y = mx + b
Answer:
the answer is C 26cm²
Step-by-step explanation:
because we are looking at the square centimetre
