Answer:
y+what ever the angle inside=180 since its on a line
180-128=52
52+z+x=180since thats always the angles of a triangle added up
52+91+x=180
add
143+x=180
-143
x=37
Hope This Helps!!!
Answer:
y = 2x
the rise is the 2, and the the run is positive 1, because with graphing its always rise/run, and if there isn't anything below it, it is 2x/1
Similar triangles so AC:BC=AE:DE
15+6=21 = AE
15:12.5=21:?
to get from 15 to 12.5 you divide by 15 and times by 12.5 so do this the to the other side
21/15=1.4
1.4 x 12.5=17.5
So DE=17.5
Just solve the equation! if the dot means multiply, then
35 - (5 x 2) + (16 / 4) because of BIDMAS or PEDMAS or whatever abbreviation you use, where the order is Brackets Indices Division Multiplication Addition and Subtraction.
35 - 10 + 4 = 29
Therefore the answer is 29.
Hope I helped!
It's the first one you can just add or multiply the expressions to get the answer
