Answer:
1) True
2) False
3) False
4) True
Step-by-step explanation:
1) True
Anything over 100% is larger than the original.
2) False
Since it is 225% bigger, you multiply 4 by 2.25.
4 x 2.25 = 9
3) False
If it is 225% larger, it means that it is 2.25 times larger
4) True
55+p=105
subtract 55 from both sides
p=50
MAGIC
(3x + 1) + (4x - 17) + (5x - 20) = 180
12x - 36 = 180
12x = 216
x = 18
angle a = 55
angle b = 55
angle c = 70
This is an acute isosceles triangle.
Option A:
m∠B = 42.1°
Solution:
Given data:
b = 18, c = 15 and m∠C = 34°
Using sine formula:

Substitute the given values.

Do cross multiplication.

Divide by 15 on both sides.





Switch the sides.
m∠B = 42.1°
Option A is the correct answer.
