FIND THE ANGLES MEASURE x IN THE FOLLOWING FIGURES​

Answer 1

1. Sum of all angles of a quadrilateral is 360°

so x = 110°.

2. similarly x= 140°

3. x= 50°

4. x= 108°

5. x= 90°

y=120°

z= 150°

x+y+z =360°.

6. similarly x+y+z+w= 380°

Answer 2

Answer:

$(6)(a) \: \: {50}^{0} + {130}^{0} + {120}^{0} + x = {360}^{0} \\ \\ x = {60}^{0} \\ \\ (b) {70}^{0} + {60}^{0} + {90}^{0} + x = {360}^{0} \\ \\ x = {140}^{0} \\ \\ (c) \: 2x + {30}^{0} + {110}^{0} + {120}^{0} = {360}^{0} \\ \\ 2x = {100}^{0} \\ \\ x = {50}^{0} \\ \\ (d) \: 5x = {360}^{0} \\ \\ x = {72}^{0} \\ \\ (7)(a) \: \: x = {90}^{0} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: y = {120}^{0} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: z = {150}^{0} \\ \\ x + y + z = {360}^{0} \\ \\ (b) \: \: x = {60}^{0} \\ \: \: \: \: \: \: \: y = {100}^{0} \\ \: \: \: \: \: \: \: z = {120}^{0} \\ \: \: \: \: \: \: \: w = {80}^{0} \\ \\ x + y + z + w = {360}^{0}$
