Answer:
Solution given:
In right angled triangle
ABC.
with respect to <C=40°
opposite side=AB
adjacent=BC=DE=30ft
now
relationship between opposite side and adjacent
is given by tan angle
tan 40°=oppo/adjacent
tan40°=AB/30
AB=tan40*30
AB=25.2
<u>Now</u><u> </u>
<u>height</u><u> </u><u>of</u><u> </u><u>flagpole</u><u> </u><u>=</u><u>AB</u><u>+</u><u>BE</u><u>=</u><u>2</u><u>5</u><u>.</u><u>2</u><u>+</u><u>5</u><u>=</u><u>3</u><u>0</u><u>.</u><u>2</u><u>f</u><u>t</u>

Answer:
<h2>y = -9x - 2</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>y = mx + b</em>
<em>m</em> - slope
<em>b</em> - y-intercept (0, b)
We have the slope <em>m = -9</em> and the y-intercept (0, -2) → <em>b = -2</em>.
Substitute:
<em>y = -9x + (-2) = -9x - 2</em>
Answer: x=3 y=3
Step-by-step explanation:
Assuming you meant 2x+3y=15 as the first problem. You have to make either both the x’s or both the y’all equal in both equations first. Multiply the second equation by 2 (for x’s) and you’ll get 2x+2y=12. The 2x cancels out so you’re left with 3y=15 and 2y=12. Subtract 2y=12 from 3y=15 and you get y=3.
Repeat to figure out x. Multiple second equation by 3 (for equal y’s) and you get 3x+3y=18. This time the first equation is being subtracted from the second one. (3x+3y=18) - (2x+3y=15). Y’s cancel out and you’re left with (3x=18)-(2x=15. Subtract and you get x=3
