To find the area of the shape, you can split the shape into 2 shapes, a rectangle and a triangle. The area of a rectangle is A=l x w and the area of a triangle is A=1/2 bh. The are of the rectangle is 200 since 20 times 10 is 200. The area of the triangle is 20 times 4 divided by 2. The area of the triangle is 40. Add both areas to get the total are of 240. The area of the shape is 240.

If isosceles triangle ABC has a 130° angle at vertex B, which statement must be true?

scZoUnD [109]

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°

Simplify (write without the absolute value sign):<br> 120+x, if x <- 120

Alexeev081 [22]

Answer: - x - 120

Explanation: You want to find the opposite of (120-x) not just x, so you just put the negative symbol next to both the variables.
