question 4

Multiple Choice

Find the measure of each unknown angle in triangle ABC.
-
$\angle \mathrm { A } = ( 40 \mathrm { x } - 17 ) ^ { \circ } , \angle \mathrm { B } = ( 35 - 2 \mathrm { x } ) ^ { \circ } , \angle \mathrm { C } = ( 6 + \mathrm { x } ) ^ { \circ }$

• A) \(\angle \mathrm { A } = 37 ^ { \circ } , \angle \mathrm { B } = 23 ^ { \circ } , \angle \mathrm { C } = 14 ^ { \circ }\)
• B) \(\angle \mathrm { A } = 143 ^ { \circ } , \angle \mathrm { B } = 31 ^ { \circ } , \angle \mathrm { C } = 6 ^ { \circ }\)
• C) \(\angle \mathrm { A } = 143 ^ { \circ } , \angle \mathrm { B } = 27 ^ { \circ } , \angle \mathrm { C } = 10 ^ { \circ }\)
• D) \(\angle A = 37 ^ { \circ } , \angle B = 35 ^ { \circ } , \angle C = 2 ^ { \circ }\)
