What is the measure of angle C?

Enter your answer in the box.

°

Answers

Answer:

∠C = 62°

Step-by-step explanation:

GIVEN :-

Cyclic quadrilateral ABCD
∠A = (2x + 38)°
∠D = (x + 20)°
∠B = (3x)°

TO FIND :-

The measure of ∠C

FACTS TO KNOW BEFORE SOLVING :-

A cyclic quadrilateral is a quadrilateral inscribed in a circle.
In a cyclic quadrilateral , sum of the opposite interior angles is equal to 180°

PROCEDURE :-

As ABCD is a cyclic quadrilateral ,

∠B + ∠D = 180°

$=> 3x + x + 20 = 180$

$=> 4x = 180 - 20$

$=> x = (160)/(4) = 40$

Putting the values of x gives :-

∠A = (2×40 + 38)° = 118°

∠B = (3×40)° = 120°

∠D = (40 + 20)° = 60°

Also,

∠A + ∠C = 180°

⇒ ∠C = 180° - 118° = 62°

The gas tank in felizs car is 5/6 full each time he drives to or from work he uses 1/12 of a full tank of gas which equation represent the number of times feliz can drive to or from work with the gas in his tank

Answers

Answer:

Equation represent the number of times feliz can drive to or from work with the gas in his tank is $(1)/(12)x=(5)/(6)$

Step-by-step explanation:

The gas tank in felizs car is 5/6 full

When he drives to or from work he uses part of a full tank of gas =\frac{1}{12}

Let x be the number of times feliz can drive to or from work with the gas in his tank

So, He uses part of full tank of gas in x drives = $(1)/(12)x$

So, ATQ

$(1)/(12)x=(5)/(6)$

$x=(5)/(6) * 12$

x=10

The number of times feliz can drive to or from work with the gas in his tank is 10

Hence equation represent the number of times feliz can drive to or from work with the gas in his tank is $(1)/(12)x=(5)/(6)$

PLEASE HELP AND PLEASE DONT GUESS!!!!Sharon has some one-dollar bills and some five-dollar bills. She has 14 bills. The value of the bills is $30. Solve a system of equations using elimination to find how many of each kind of bill she has.
