Answer: Actually, you must use the Pythagorean Theorem!
a squared plus b squared equals c squared. So if you substitute in the values, a is 2 units and b is three units. 2 squared is 4 and 3 squared is 9.
4 + 9 = 13 so the answer is the square root of 13. (√13)
Answer:
No
Step-by-step explanation:
Given: Angles of a triangle are equal to 90 degrees , 50 degrees, and 60 degrees
To check : if it possible to build a triangle with given angles
Solution:
According to angle sum property of a triangle, sum of angles of a triangle is equal to 
Here,
sum of given angles = 
Therefore, it is <u>not possible</u> to construct a triangle with given angles.

Explanation:
Line AE is a tangent while line AU is a secant. The angle formed by the secant and tangent lines connects with the arcs through this formula
secant tangent angle = (larger arc - smaller arc)/2
More specifically, we can say:
angle EAI = (arc EU - arc IE)/2
42 = ( (7m+5) - (3m-1) )/2
42*2 = (7m+5) - (3m-1)
84 = 7m+5 - 3m+1
84 = 4m+6
4m+6 = 84
4m = 84-6
4m = 78
m = 78/4
m = 39/2
m = 19.5
Use this value of m to compute each arc
- arc IE = 3m-1 = 3*19.5-1 = 57.5 degrees
- arc EU = 7m+5 = 7*19.5+5 = 141.5 degrees
Let's say arc IU is some unknown number x. It must add to the other two arc measures to form 360 degrees, which is a full circle.
(arc IU) + (arc IE) + (arc EU) = 360
x + 57.5 + 141.5 = 360
x + 199 = 360
x = 360-199
x = 161
The measure of minor arc IU is 161 degrees
