Answer:

a) x = 88/1.1 = 80

b) z = 5.6

c) w = 18

Step-by-step explanation:

a) Not much to say here, divide both sides by 1.1

b) Subtract 2.34 from both sides to isolate z and you will get 5.6

c) You can multiply each side by 3 first than divide by 2 OR you can multiply both sides by 3/2 to get w = 18.

What is the measure of angle A?
fgiga [73]

Answer:

∠A=65º

Step-by-step explanation:

  • A angle of a line is 180º, so we can say that angle ABC=(180-6x)º
  • The interior angkes of a triangle is 180º, so (x+40)º+(3x+10)º+(180-6x)º=180º
  • Remove parenthesis, x+40+3x+10+180-6x=180
  • Combine like terms, -2x+230=180
  • Subtract 180, -2x=-50
  • Divide by -2, so x=25

Now:

  • ∠CAB=(25+40)º=65º
  • ∠ABC=[180-6(25)]º=30º
  • ∠BCA=[3(25)+10]=85º

4) The triangle on the right is an equilateral <br><br> Find the value of X and Y
ozzi

Answer:

<em>angle Y is 29 degrees</em>

<em>angle X is 120 degrees</em>

Step-by-step explanation:

Well, if the triangle is an equilateral, then all the angles are equal to

60 degrees

that means the the angle at the top point is 60+31 = 91 degrees

the right point is 60 degrees

every triangle has 180 degrees total

180 - (91+60) = 29 degrees

NOW FORGET ABOUT THE EQUILATERAL FOR A BIT

180 = 31+x+29

simplify

180 = 60+x

subtract 60 from both sides

120 = x
