Answer:

x = 35

Step-by-step explanation:

Angle JML is 90 degrees

3x-15 = 90

Add 15 to each side

3x-15+15 = 90+15

3x = 105

Divide each side by 3

3x/3 =105/3

x = 35

DanielleElmas [232]

Answer:

d

Step-by-step explanation:

Volume can be described as the total amount of space that is in a closed surface. this amount of space is usually three dimensional. Volume is usually measured in m³ or cm³ or in³

For example,  the volume of a rectangular box given the following dimension : length - 3cm

breadth - 8cm

height - 10 cm

volume = length x width x height = 8 x 3 x 10 = 240 cm³

What is mLA?<br><br> Enter your answer in the box.
olga nikolaevna [1]

Answer:

84 degrees

Step-by-step explanation:

To find the measure of angle a you must first find m<CED. To do this remember every triangle has a measure of 180.

180-(43+35)=102, that means m<CED=102. Also m<CED=m<AEB because they are vertical angles. So now do the same operation but for the other triangle 180-(102+18)=84. So m<A=84.
