Ineed in the next 20 mins plz find b. enter only the number.

b = 35°

Step-by-step explanation:

Given : A triangle with one angle 90° and one angle 55°

We need to find the value of b,

Lets name the the given figure as shown below.

Now consider ΔPQR,

Angle sum property states that the sum of angles of a triangle is always 180°

Applying Angle sum property, we get,

∠P + ∠Q + ∠R = 180°

Substitute the values, we get,

⇒ 90° + 55° + ∠R = 180°

⇒  145° + ∠R = 180°

⇒ ∠R = 180°- 145°

⇒  ∠R = 35°

Thus, value of a is 35°

Since a and b forms a pair of vertically opposite angles.

Thus, ∠QRP =  ∠SRT = 35°

Thus, b = 35°

step-by-step explanation:

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
