Answer:
Option B m<ZA+m<ZB = 155° is correct option.
Step-by-step explanation:
We know that sum of angles of triangle is equal to 180°
And Isosceles triangle, 2 angles are same
So, let Angle 1 = x
Angle 2 = x
Angle 3 = 130°
Finding values of angle x
x+x+130=180
2x=180-130
2x=50
x=25
So, Angle 1 = 25 °
Angle 2 = 25°
As, angle B is greater than 90°, the sum of angles added must be greater than 90°
So, Option A, C and D can't be correct, as their sum is less than 90°
Option B m<ZA+m<ZB = 155° is correct option.
Verify:
m<ZA = 25° (as found earlier)
m<ZB = 130° (given)
So, m<ZA+m<ZB = 155°
25°+130° = 155°
Answer:

Step-by-step explanation:
We will solve the given expressions and find the answer in decimals.
1).
= 
= 5.4 - 2.8
= 2.6
2). 
= -3.3 + 0.35
= -2.95
3).
= -3.125
4). (-4.5) × (-2.3) = 10.35
Solution of the expressions in the increasing order will be,
-3.125 < -2.95 < 2.6 < 10.35

C. Metamorphic rock -> melting -> solidification
Let silk shirts be x,so tie dye shirts 5x.
X+5x=240
6x=240
X=40
So 5x=200
