In triangle Xyz the measure of angle YXZ is 14.5°, and the measure of angle XYZ is 75°. What is the measure of angle XZY in degr
steposvetlana [31]

Answer:

90.5 degrees

Step-by-step explanation:

The sum of the angle in triangle XYZ is 180 degrees, hence;

m<XYZ + m<YXZ + <XZY = 180

Substitute the given angles

75 + 14.5 + <XZY = 180

89.5+m<XZY = 180

m<XZY = 180 - 89.5

m<XZY = 90.5 degrees

Hence the measure of angle XZY in degrees is 90.5 degrees

Write an equation of a line parallel to y=1/2x+3 that passes through (2,5)
tamaranim1 [39]
y=\frac{1}{2}x+3 \parallel y=mx+b

Two lines are parallel when their slopes are the same.
m=\frac{1}{2} \\ y=\frac{1}{2}x+b \\ \\ (2,5) \\ x=2 \\ y=5 \\ \Downarrow \\&#10;5=\frac{1}{2} \times 2 + b \\ 5=1+b \\ b=4 \\ \\ \boxed{y=\frac{1}{2}x+4}&#10;

The difference of the square of a number and 28 is equal to 3 times that number
Pepsi [2]

Answer:

- 4, 7

Step-by-step explanation:

Let the required number be x.

Therefore, according to the given condition:

{x}^{2}  - 28 = 3x \\  {x}^{2}  - 3x - 28 = 0 \\  {x}^{2}  - 7x + 4x - 28 = 0 \\ x(x - 7) + 4(x - 7) = 0 \\ (x - 7)(x + 4) = 0 \\ x - 7 = 0 \: or \: x + 4 = 0 \\ x = 7 \: or \: x =  - 4 \\
