Okay, you now a triangle has 180º degrees and to add to 180º, you have to add all the numbers you have like this:
2x+x+90 (the box is 90º)=180º; add like terms like 2x+x
3x+90=180; cancel 90 by subtracting it and also subtract 90 from 180
3x=90;divide 3 to isolate x and also divide 90/3
x=30 :)
Answer:
152 sq. ft
Step-by-step explanation:
to determine the square you multiply the length by the width (16 by 8)
to determine to area of the triangle you must subtract 12 by 16 in order to get the length of the triangle. then multiply the length (4) of the triangle by the height of the triangle (6)
finally add the areas of the triangle and square together to get the total length of the whole thing.
Answer:
it is a slope intercept form
