Answer:
152°
Step-by-step explanation:
If two pairs of congruent angles total 360°, then the different angles must total 180°. The other angle measure is 180° -28° = 152°.
The measure of each angle in the other congruent pair is 152°.
Answer: Vertical angles
Step-by-step explanation:
Answer:
sin(θ) = sin(θ + 2π) = -sin(-θ)
b and d
This can be shown by substituting a value for θ
sin(π ÷ 3) = 1/2
sin(π ÷ 3 + 2π) = 1/2
-sin(π ÷ 3) = -1/2
-sin(-π ÷ 3) = 1/2
sin(π ÷ 3 + π ÷ 2) = √3/2
<h3>(-3j²k³)²(2j²k)³</h3>
(-3j²k³)²(2j²k)³ = <em>When a power is raised to a power the exponents have to be multiplied.</em>
= (-3²j⁽²*²⁾k⁽³*²⁾)(2³j⁽²*³⁾k³) = <em>We can take out the constants</em>
= (9)(8)(j⁴k⁶)(j⁶k³) = <em>We can group the same variables</em>
= 72(j⁴j⁶)(k⁶k³) = <em>When multiplying two powers that have the same base, you have to add the exponents.</em>
= 72 j⁽⁴⁺⁶⁾k⁽⁶⁺³⁾ = 72j¹⁰k⁹
Answer = 72j¹⁰k⁹
Hope this helps!
Answer:
A≈ 50.27
Step-by-step explanation:
A=πr^2
8 divided by 2 to get the radius which is 4
π4^2
π4^2 = 50.27
