Find the values of x, y and z.

Answers

Answer:

X = 53 degrees

Y = 74 degrees

Z = 53 degrees

Step-by-step explanation:

So if you knew that all angles in triangles add up to 180 degrees. You first want to find Y. 180 - 36 - 70 is equal to 74. So, Angle Y is 74 degrees. Line XYZ is a line that has a 180 degree on there. So 180 - 74 and divide that by 2 to find X and Z. 180 - 74 is 106. 106/2 = 53. Therefore, X and Z are 53 degrees, Y is 74 degrees.

Y =74

Step-by-step explanation:

Add the number till u get 180

[tex] \frac{ \sqrt{7} }{2} [/tex]

Step-by-step explanation:

The triangle is an isosceles triangle. Because the triangle is an isosceles triangle, the height and base of the triangle are equal to eachother.

a² + b² = c²

right now we have c² which is 7

a² + b² = 7

[tex] \frac{ \sqrt{7} }{2} [/tex]

because a² and b² are = to eachother

Answer:

∠QSR = 78°∠SQR = 51°

Step-by-step explanation:

The measure of an inscribed angle (QTR) is half the measure of the arc it intercepts. The measure of an arc is the same as the measure of the central angle it intercepts. So, we have ...

  ∠QSR = 2×∠QTR

  ∠QSR = 2×39°

  ∠QSR = 78°

__

Sides SQ and SR are radii of circle S, so are the same length. That means triangle QRS is an isosceles triangle and the base angles SQR and SRQ are congruent. The sum of angles in a triangle is 180°, so we have ...

  ∠QSR + 2(∠SQR) = 180°

  78° + 2(∠SQR) = 180° . . . . fill in the value we know

  2(∠SQR) = 102° . . . . . . . . . subtract 78°

  ∠SQR = 51° . . . . . . . . . . . . .divide by 2
