Answer:
80°
Step-by-step explanation:
The sum of the angles of a triangle is always 180°.
∴ 2x + 3x + 5x = 180°
10x = 180°
x = 180 / 10
x = 18
The biggest angle = 5x
= 5 * 18
= 90°

Answer:
RM = MS = 3
Step-by-step explanation:
Answer:
3x - y = 8
y = 3x - 8
y = 3*2.5 - 8 = -0.5 --> (2.5, -0.5)
y = 3*5 - 8 = 7 --> (5, 7)
Answer C is correct.
Answer:
Tanaysha replace 8 by ( 10 -2) to solve the given expression.
Step-by-step explanation:
Here, the given expression to be solved is:
72 - 8 .......... (1)
Now, as we know: 8 = 10 - 2
Replacing the value of 8 with ( 10 - 2), we get:
72 - 8
= 72 - (10 - 2)
= 72 - 10 + 2
= (72 + 2 ) - 10
Now, adding ( 72 ) and ( 2) , we get:
= 74 - 10
Subtracting 10 from 74, we get:
= 64
So, Tanaysha replace 8 by ( 10 -2) to solve the given expression.
8−3(6−6a)
Distribute:
=8+(−3)(6)+(−3)(−6a)
=8+−18+18a
Combine Like Terms:
=8+−18+18a
=(18a)+(8+−18)
=18a−10
