Complete Question:

In Rhombus QRST, diagonals RT and QS are drawn. If m<TSR = 104°, then which of the following is the measure of <SRT?

Sicne triangle STR is isosceles, hence the base angles are equal. Let the base angles be y

y+y+104 = 180

2y = 180-104

2y = 76

y = 38degrees

Since <STR = y, hence the measure of <STR = 38degrees

Solve the equation x-13+4x=22 a: 1.8 b: 5 c: 7 d: 11.7

Hunter-Best [27]

Answer: x=7

first, collect like terms:
5x-13=22

next move the constant to the right-hand side and change its sign:
5x=22+13

then add:
5x=35

lastly divide both sides of the equation by 5:
and you get.... x=7

hope this helps!! :))
