What is the value of x if a triangle has angle measurements of x°,90°, (2x+21) °?

Simple. A triangle adds up to 180 degrees in total of its 3 angles.

So the sum of all of these angles are 180.

Solve the equation now:

x+90+2x+21=180

3x+111=180

3x=180–111

3x=69

x=23

The value of x is 23. But to be extra, let’s find out the last angle

2x+21 just substitute x=23

2(23)+21

=46+21

=67

Therefore, the angles of the triangles are: 67, 23 and 90.
