What is the value of M
Serggg [28]

m∠a = 56°, m∠b = 34°, m∠c = 56°

Solution:

<em>Sum of the adjacent angles in a straight line is 180°.</em>

⇒ m∠a + 124° = 180°

⇒ m∠a = 180° – 124°

⇒ m∠a = 56°

∠a and ∠c are vertically opposite angles.

Vertical angle theorem:

<em>If two lines are intersecting, then the vertically opposite angles are congruent.</em>

⇒ ∠a ≅ ∠c

⇒ m∠a = m∠c

⇒ m∠c = 56°

<em>Sum of the adjacent angles in a straight line is 180°.</em>

m∠b + 90° + m∠c = 180°

m∠b + 90° + 56° = 180°

m∠b + 146° = 180°

m∠b = 180° – 146°

m∠b = 34°

Hence m∠a = 56°, m∠b = 34°, m∠c = 56°.

Can someone help with number 1? i’ll give brainliest ;)
Butoxors [25]

Answer:

Hey there!

She wants an 93, so we write the equation: \frac{87+96+98+90+92+x}{6}=93

Multiply both sides by 6 to get: 87+96+98+90+92+x=558\\

Simplify: 463+x=558

Subtract 463 to get that x=95.

Thus, she must score a 95 to get a A as a final grade.

Hope this helps :)
