Question

Solve for in the diagram below. (2x + 45° 7 RO 7 -

Answer 1

Answer:

x = 45°

Step-by-step explanation:

The sum of both angles should add up to 180°, because they are supplementary. Supplementary angles is just another way of saying two angles on a straight line. In order to find the value of x:

Given |

$2x + 45 + x = 180$

2x + x

Combine like-terms. |

$3x + 45 = 180$

180 - 45

Subtraction Property of Equality. |

$3x = 135$

135 / 3

Division Property of Equality. |

$x = 45$

Answer 2

Answer:

45°

Step-by-step explanation:

The angles should add to 180°. so we can say 2x+45+x=180

3x+45=180

3x=135

X=45°
