Answer:
The value of x is 65° and the value of y is 155°
Step-by-step explanation:
Refer the attached figure
In triangle ABC
<u>Angle sum property of triangle</u> : Sum of all angles of triangle is 180°
So, 25°+90°+x=180°
115°+x=180°
x=180°-115°
x=65°
<u>Exterior angle property </u>: An exterior angle of a triangle is equal to the sum of the two opposite interior angles
So, 90°+x=y
So, 90°+65°=y
155°=y
Hence The value of x is 65° and the value of y is 155°
The answer is to the question is y=-2x+11
Answer:
9x + 4y < 110
Step-by-step explanation:
This inequality works because its the cost of hammers ($9) multiplied by how many hammers are bought (x) plus the cost of wrenches ($4) multiplied by how many wrenches are bought (y). The total cost has to be less than 110.
Since x is a tangent to the cercle we have the following formula:
x² = (29).(29+130) = 4611
x = √4611
x= 67.9 ≈ 68 in
