Please help me! and explanation on how you got it please
Igoryamba

Answer:

Step-by-step explanation:

This is a right angled triangles and the summation of the other two angles must equal 90°

OR you can also say that the summation of all the angles in a ∆ must give us 180°

Therefore (2x+14) + (4x-26) = 90°

Expanding... By collecting all like terms, we have

2x+4x+14-26-90 = 0

6x - 102° = 0

Therefore, 6x = 102

x = 102/6

x = 17°

Solve the system of equations by substitution and show work.<br> ​​y=−6x+13<br> y=3x+4
sukhopar [10]

Answer: x= 1 , y = 7

Step-by-step explanation:

y = -6x + 13 ................. equation 1

y = 3x + 4 ................ equation 2

substitute y = 3x + 4 into equation 1 , then we have

3x + 4 = - 6x + 13

collect the like terms , we have

3x + 6x = 13 - 4

9x = 9

x = 1

substitute x = 1 into equation 2 , we have

y = 3(1) + 4

y = 3 + 4

y = 7

Therefore : x = 1 and y = 7
