Angle RST is a right angle. Angle RSU has a measure of 25°. Lines R S and S T connect to form a right angle. Another line extends from point S to point U. Angle R S U is 25 degrees. What is the measure of angle TSU? 25° 45° 65° 75°

The measure of ∠TSU = 65°

Step-by-step explanation:

Since RST is a right-angled triangle and RS and ST connect to form a right angle, ∠RST = 90°. Also, since RS and ST connect to form a right angle, ∠RST = ∠RSU + ∠TSU.

We make ∠TSU subject of the formula. So,

∠TSU = ∠RST - ∠RSU

Given that angle ∠RSU = 25° and ∠RST = 90°, substituting these values into he expression for ∠TSU, we have

∠TSU = ∠RST - ∠RSU

∠TSU = 90° - 25°

∠TSU = 65°

So, ∠TSU = 65°

The measure of ∠TSU = 65°

65

Step-by-step explanation:

you know it forms a right angle because of the marking on it

so take 90 because thats the degree of a right angle, and subtract 25 from it and you will get your other side

90-25=x

65=x

check by adding both angles

65+25=90
