Answer:

one angle: 51° and other angle: 39°

We can simply find:

  • complementary angle is when two angles add up to 90°
  • let one angle be x
  • then the another angle will be [ x - 12° ]

Solve:

x - 12 + x = 90

2x = 90 + 12

x = 51°

one angle → 51°

other angle: x - 12 → 51° - 12 → 39°

Let ∠1 be x

Let ∠2 be x-12

<h3>ATQ,</h3>

\rm(x - 12 )+ x = 90 \degree

\rm2x - 12 = 90 \degree

\rm2x = 90 + 12

\rm2x = 102

\boxed{ \bf \: x = 51 \degree}

<h3>So,</h3>

\sf \: ∠1 = x \\  \sf \:  = 51 \degree

\sf \: ∠2 = x - 12 \\  \sf  = \: 51 - 12 \\  \sf∠2 = 39 \degree

PLEASE HELP Solve the following problems: Find the indicated values, mAB, m ABC, mBAC, mACB
alekssr [168]
It already shows that AB is 49°

in order to find ABC you must first find BC

360 - (AC + AB) = BC
360 - 156 = BC
204° = BC

NOW add BC with AB

49 + 204
253

angle ABC is 253°

now to find BAC add AB and AC
49 + 107 = 156°

angle BAC is 156°

FINALLY to find ACB add AC and CB

107 + 204
311°

angle ACB is 311°
