Step-by-step explanation:
l = prt
r = l/pt
Answer:
other acute angle = 81°
Step-by-step explanation:
right angle has 90°.
here given one angle is 9°
total angle in a triangle is 180°
90° + 9° + x = 180°
x = 81°
The answer is C. From the solution in the picture
If you would like to solve the inequality <span>–1 + 6 * (–1 – 3x) > –39 – 2x, you can do this using the following steps:
</span>–1 + 6 * (–1 – 3x) > –39 – 2x
-1 - 6 - 18x > -39 - 2x
-7 + 39 > -2x + 18x
32 > 16x
32/16 > x
x < 2
The correct result would be x < 2.
Answer:
infinite number
Step-by-step explanation:
Carry out the multiplication indicated here:
5x + 3(x-5) = 6x + 2x -15 => 5x + 3x - 15 = 6x + 2x -15
Now combine the x terms: We get 8x - 15 = 8x - 15, or -15 = -15.
This last result is always true, so this equation has an infinite number of solutions.
