Answer:
∠ I = 39°, ∠ J = 51°, ∠ K = 90°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the3 angles and equate to 180
3x + 21 + 5x + 21 + 90 = 180, that is
8x + 132 = 180 ( subtract 132 from both sides )
8x = 48 ( divide both sides by 8 )
x = 6
Then
∠ I = 3x + 21 = 3(6) + 21 = 18 + 21 = 39°
∠ J = 5x + 21 = 5(6) + 21 = 30 + 21 = 51°
∠ K = 90°
Answer:
1 7
-120 -22
Step-by-step explanation:
you need to do top left top right bottom left bottom. in order to move x to the other side you need to subtract then divide by the negative.
I did the math,This is false.
Hope this helps.
Answer:
$5000 is how much he borrowed or the "principle" amount.
Step-by-step explanation:
The formula for simple interest is: I = p * r * t
where I = the interest charged, p = principle or amount borrowed, r = the annual rate charged (changed from a percent to decimal by dividing by 100) and t = time (must be expressed in year)
So, I = prt
750 = p * .05 * 3 (here, 3 * .05 = 0.15)
<u>750</u> = <u>0.15p</u> (now you need to solve for p by dividing both sides of the
0.15 0.15 equation by .15
5000 = p
So the amount borrowed is $5000
Answer:
73cm²
Step-by-step explanation:
Area of rectangle=½ length×width
=½×18×7
=63cm²
Area of triangle=½b×h
base=18-13= 5cm
height=11-7 =4cm
½×b×h
½×5×4
=10cm²
Area of total=63+10
73cm²
