Answer: angle 2 is 49°
explanation: the interior angles of all triangles add up to 180°, so just subtract the known angles from 180 to get the unknown angle:)
Answer:
One Angle = 110°
Other Angle = 70°
Step-by-step explanation:
A linear pair means that two angles are in a straight line (or, a straight angle).
A straight line is 180 degrees.
THey are supplementary.
We can say one angle is "a" and another one is "b".
<em>One angle is 10 MORE THAN 2/3rds of the other, we can write:</em>
<em>
</em>
<em />
<em>Also, since they are supplementary (add up to 180), we can write:</em>
<em>a + b = 180</em>
<em />
We can now substitute 1st equation in this one and find b:

Since a + b = 180, we can write:
a + 110 = 180
so,
a = 180 - 110
a = 70
Thus,
One Angle = 110°
Other Angle = 70°
Answer:
r=7
Step-by-step explanation:
-84+15r=3r
Subtract 15r from each side
-84+15r-15r=3r-15r
-84 = -12r
Divide each side by -12
-84/-12 = -12r/-12
7 = r
Answer:
18
Step-by-step explanation:
30 ÷ 2 =15
36 ÷ 2 = 18
The difference between them is 2, so let the unknown numbers be x and (x+2).
<span>Their sum is 52, so: </span>
<span>52 = x + (x+2) </span>
<span>52 = x + x + 2 </span>
<span>50 = x + x </span>
<span>50 = 2x </span>
<span>25 = x </span>
<span>So your unknown numbers x and (x+2) are 25 and 27.</span>
