Answer:

12+40= 52

180-52=128

Step-by-step explanation:

Angles in a triangle add up to 180

so if two sides are given , they must be added and subtracted from 180.

which gives us 180-52=128

How many triangles can be constructed with sides measuring 1 m, 2 m, and 2 m?
Margaret [11]
Answer: B
Explanation: ONE triangle can be formed.
According to the triangle inequality theorem, the sum of any two sides must be greater or equal than the length of the third side.
Here, the sides are 1 m, 2 m, and 2m. 1m + 2m = 3m > 2m (theorem followed) 2m + 2m = 4m > 1m (theorem followed)
Since, the triangle inequality theorem is followed, Hence, ONE triangle can be formed.

PLS Help im sooo stuck on this question pls help and show your work and please dont put a nonsense answer
Snowcat [4.5K]

XY = xZ

85b + 83 = 91b - 283

Subtract 85b from both sides:

83 = 6b - 283

Add 283 to both sides:

6b = 366

Divide both sides by 6:

B = 61

Now replace b with 61 and solve for the length:

85(61) + 83

5185 + 83 = 5268

The length is 5,268
