The sine of one acute angle is equal to the cosine of another when their sum is 90°.
.. (2β +10°) +(3β -25°) = 90°
.. 5β -15° = 90°
.. 5β = 105°
.. β = 21°
Then your equation becomes
.. sin(52°) = cos(38°)
Answer:
It is B. H = 3d
Step-by-step explanation:
I got it right :)
1. An angle that is between 0° and 90° is an ACUTE ANGLE.
2. Angles, segments, triangles, etc that have exactly the same measures are CONGRUENT.
3. Two angles that add up to 180° are SUPPLEMENTARY ANGLES.
4. Angles that are opposite to one another at the intersection of two lines are VERTICAL ANGLES.
5. Two angles in a common plane which share a common Bertrand a common side but do not overlap are ADJACENT ANGLES.
6. Two angles that add up to 180° that share a common vertex are ADJACENT SUPPLEMENTARY ANGLES.
7. Two angles that are located between two coplanar lines on opposite sides of the transversal are ALTERNATE INTERIOR ANGLES.
8. Two angles that are located outside two coplanar lines on opposite sides of the transversal are ALTERNATE EXTERIOR ANGLES.
9. Two angles that are located between two coplanar lines on the same side of the transversal are CONSECUTIVE INTERIOR ANGLES.
10. Two angles that are formed by two coplanar lines and a transversal and occupy the same relative positions are CORRESPONDING ANGLES.
11. An angle that is 180° is a STRAIGHT ANGLE.
Answer:
The solution to the question is g = 52
Step-by-step explanation:
Here, we want to find the solution to the equation ;
98 + g = 150
Apparently, we want to find the value of g.
To get the value of g, what we simply need is to bring 98 over the equal sign and this gives
g = 150-98
g = 52
