Triangle ABC has angle measures as shown A x-5 B 3x+30 C 35 qhat is the value x

Vinvika [58]

Answer:

$x=30\ degrees$

$m$

Step-by-step explanation:

we know that

The sum of interior angles in a triangle must be equal to 180 degrees

$(x-5)+(3x+30)+(35)=180\°$

solve for x

$4x=180\°-60\°$

$4x=120\°$

$x=30\°$

$m$

In the given diagram , TY is a tangent to the circle TVS . If <SVT = 48° and |VS| = |ST| . What is < VTY.

ycow [4]

Answer:

84°

Step-by-step explanation:

∠VTY is the tangent chord angle

Tangent chord angle is the half of the intercepted arc

∠TSV is the inscribed angle.

Inscribed angle is the half of the intercepted arc

Since both of the mentioned angles refer to same arc, they are of same value.

∠VTY = ∠TSV

ΔTVS is isosceles as VS = ST, therefore the opposite angles are same.

m∠T = m∠V = 48°

The measure of angle S

m∠S = 180° - 2*48° = 84°

The required angle

m∠VTY = 84°
