Angles a and b are ertical angles the measure of angle a is 8x+1 and angle b is 21-2x find each angle measure
Answers
Answer:
Angle a = 17°
Angle b = 17°
Step-by-step explanation:
Angles a and b are vertical angles the measure of angle a is 8x+1 and angle b is 21-2x find each angle measure
Vertical angles are angles that are equal to each other
Step 1
We find x
a = b
Hence,
8x+1 = 21-2x
Collect like terms
8x + 2x = 21 - 1
10x = 20
x = 20/10
x = 2
Step 2
We find each angle
Angle a
8x+1
x = 2
Angle a = 8(2) + 1
= 17°
Angle b
21-2x
x = 2
21 - (2 × 2)
= 21 - 4
= 17°
Therefore:
Angle a = 17°
Angle b = 17°
The radius of a circle is (2x-3). What is a function for the area of the circle?
Answers
Answer
A = pi * r^2
= pi * (2x^-3)^2
= pi * 2^2 * (x^-3)^2
= pi * 4 * (x^-6)
= 4*pi * x^-6

Answers
Given:
A figure ABCP.
To find:
The measure of CP.
Solution:
In triangles ABP and CBP,
[tex]\angle PAB\cong \angle PCB[/tex] (Given right angles)
[tex]\angle ABP\cong \angle CBP[/tex] (Given)
[tex]BP=BP[/tex] (Common side)
Now,
[tex]\Delta ABP\cong \Delta CBP[/tex] (By AAS property of congruence)
We know that the corresponding parts of congruent triangles are congruent.
[tex]AP=CP[/tex]
