Answer:
a. x=40 b. x=19
Step-by-step explanation:
a. 40+40= 80
80+10=90
90=right triangle
b. 3 x 19= 57
57+19
76+14= 90
90=right triangle
Answer:
x = 20
Step-by-step explanation:
These two angles are equal:
5x + 7 = 6x - 13
Subtract 5x from both sides.
7 = x - 13
Add 13 to both sides.
20 = x

Answer:
The answer will be C
If u want just slove and see
First check to see if you have a triangle at all. Add the two short dimensions. If the sum is STRICTLY GREATER THAN the long side, then you have a triangle and you can proceed. (If the sum of the two short sides is equal to the third side, then you have a straight line -- not a triangle. If the sum of the two short sides is less than the third side, then you have two short sides flapping around unable to meet in a third vertex.)
Square the measures of each of the sides and then sum the squares of the two short sides.
If the sum is equal to the square of the long side, then you have a right triangle.
The answers are A, C, and D. B is not a correct answer because 4 times 11 is not 42
