Answer:
The measure of ∠c is 50°.
Step-by-step explanation:
When it comes to problems like these, there are two types of angles that should be kept in mind: complementary angles and supplementary angles.
Complementary angles are angles that add up to 90° (a right angle). Supplementary angles are angles that add up 180° degrees (a straight angle). A good way to recall this information in layman's terms is to remember this: complements are always right.
So now let's apply what we've learned to the problem. We have a straight angle that is composed of two 65° angles and an unknown C angle. We know that when angles add up to 180°, they're supplementary angles.
<u>If we interpret our problem in algebriac form, we can say that:</u>
65° + 65° + m∠C = 180°
<u>Now we just solve this problem like any other algebriac equation. First, you can combine like terms.</u>
130° + m∠C = 180°
<u>Then, subtract 130° on both sides to isolate our variable.</u>
m∠C = 50°
<u>Now we can safely say that the measure of angle C is 50°.</u>
I am pretty sure it is 0.95. This is because 0.5 is half of a whole. So, half of 1.9 is 0.95. :) I hope this helped.
The names PNM and MPN are perfectly valid. The order of the letters doesn't matter. In fact, there are 6 ways to name this plane if we just use the 3 letters. If we include "plane Z", then there are 7 total ways to name the plane.
For some reason, your teacher wants P to be the third letter as s/he mentioned MNP and NMP. But again, the order doesn't matter.
Answer:
145°
Step-by-step explanation:
x°+70°=(2x-5)°
x°+70°=2x°-5°
70°+5°=2x°-x°
75°=x°
x=75
JKM=(2x-5)°
=(2x75-5)°
=(150-5)°
=145°
