Use the properties of vertical angles to find the value of x. A)3
B)5
C)7
D)9

What is the measure of ∠A?
A)157°
B)159°
C)161°
D)163°​

The value of x= 7 and that of Angle A= 157°

Step-by-step explanation:

(x+16)° = (4x-5)° [Vertically opposite angles]

3x= 21

x= 7

Now, A + (4x-5)° = 180° [Linear pair]

A + [4(7)-5] = 180°

A + 23 = 180°

A = 180° - 23

A = 157°

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

mean, 40.6
