First, we need to find angle B.
53 ° + 90 ° = 143 °,
180 ° – 143 ° = 37 ° (angle B).
And so we learned that in the triangle BCH the angle B = 37 °, the angle H = 90 ° and it remains to find the angle C.
90 ° + 37 ° = 127 °,
180 ° – 127 ° = 53 ° (angle C).
Answer: in triangle BCH, the angle BCH = 53 °.
