Answer 1

option (c) 90° is the right answer

Answer 2

➻ Answer :

option c) 90°

$\huge \star \: \underline{\red{ \sf \: solution : }}$

➻ Given :

• a = 50°
• b = 15°
• c = 25°

➻ To Find :

• x
• y
• z

➻ Solving :

Name the triangle as ABC

$\\ \large \mapsto \: \sf \: in \: \: \triangle abc :$

• Angle Sum Property :

$\\ \large \tt \leadsto \: a + b + y + c + z = 180 \degree \\ \\ \large \implies \tt \: 50 \degree + 25 \degree + y + 15 \degree + z = 180 \degree$

$\\ \large \implies \tt \: 90 \degree + y + z = 180 \degree \\ \\ \large \tt \implies \: y + z = 180 \degree - 90 \degree \\ \\ \large \underline{ \boxed{\sf \therefore \: y + z = 90 \degree}}$

Finding x :

• Angle Sum Property

➢ x + y + z = 180°

$\\ \large \tt \implies \: x + 90 \degree = 180 \degree \\ \\ \large \underline{\boxed{ \green{ \therefore \tt \: x = 90 \degree}}}$
