Write the following statement as a conditional statement. stars have ten vertices. a. if a figure has ten vertices, then it is a star. b. a figure is a star, if and only if, it has ten vertices. c. star are figures with ten vertices. d. if a figure is a star, then it has ten vertices.

Correct choice is D

Step-by-step explanation:

A conditional statement, symbolized by is an if-then statement in which p is a hypothesis and q is a conclusion.

Given statement: "Stars have ten vertices", consider statements:

p="A figure is a star",

q="A figure has 10 vertices".

Then the conditional statement   sounds as "If a figure is a star, then it has ten vertices."

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
