In the answer to a right triangle the hypotenuse is 15 cm and one of the legs measures 12 cm.Qual is the perimeter of this rectangle?
edge a = 12 units
Edge b = 9 units
edge c = 15 units
The angle = 53.1 degrees
angle B = 36.9 degrees
area = 54 square units

Answer:
slope =
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 2, - 1) and (x₂, y₂ ) = (4, 3)
m = = =
12) x = 100°, y = 80° and z = 160°
13) x = 65°
Solution:
<u>Question 12</u>:
<em>If a tangent and a chord intersect at a point on a circle, then the measure of each angle formed is one half of the intercepted arc.
</em>
⇒ x = 100°
<em>Sum of the adjacent angles in a straight line is 180°.
</em>
x + y = 180°
100° + y = 180°
Subtract 100° from both sides, we get
y = 80°
By the above mentioned theorem,
Multiply by 2 on both sides, we get
⇒ 160° = z
Therefore, x = 100°, y = 80° and z = 160°.
<u>Question 13</u>:
<em>If two chords intersects in the interior of the circle, then the measure of each angle is one half the sum of the measures of the arcs intercepted by the angle and its vertical angle.
</em>
⇒ ∠x = 65°
Therefore x = 65°.
