A ratio can be defined as the relationship or comparison between two numbers of the same unit to check how bigger is one number than the other one. For example, if the number of marks scored in a test is 7 out of 10, then the ratio of marks obtained to the total number of marks is written as 7:10.

(Geometry) PART A Find the value of X.

guapka [62]

Answer:

Part A: The answer is B.

As vertically opposite angles are equal

x+10=4x-35

10=3x-35

45=3x

x=15

Part B: The answer is D.

We'll substitute in the value of X in one equation.

x+10

=15+10

=25

As the two angles are equal bot must be 25 degrees.

gulaghasi [49]

Answer:

65 degrees

Step-by-step explanation:

<u>Step 1: Find what the measure of JLK is</u>

JLM + JLK = 180

140 + JLK - 140 = 180 - 140

JLK = 40

<u>Step 2: Find what the measure of KJL is</u>

KJL + JLK + JKL = 180

KJL + 40 + 75 = 180

KJL + 115 - 115 = 180 - 115

KJL = 65

Answer: 65 degrees
