Answer:
x ≈ 2.29 cm
Step-by-step explanation:
From the picture below we are given a right angle triangle and asked to find the value of x. We can use the SOHCAHTOA principle to find the side x.
Base on the angle given the adjacent side of the triangle is x while the hypotenuse is given as 4 cm. Let's find the value of x .
cos 55° = adjacent/hypotenuse
cos 55° = x/4
cross multiply
x = 4 cos 55°
x = 4 × 0.57357643635
x = 2.2943057454
x ≈ 2.29 cm

The base of trapezoid is equal to a = 25.5 cm and b = 43.5 cm.
The area of trapezoid is A = 1656.
The formula for the area of trapezoid is,
Substitute the values in the formula to obtain the height of trapezoid.
So height of trapezoid is 48 cm.
Answer:
14,300,000
Step-by-step explanation:
Starting off with 14 million, you haven't reached the 100 thousands or below yet where you should start. The next digit, 3, is in the 100 thousands place and the digit next to it is four. When you're rounding, if the digit is greater than five, then you round up. (example: if the number you're rounding is 67, seven is greater than five so you would round it to 70.) If the digit you are rounding is smaller than 5 then you would round down. (Example: if the number you're rounding is 34, then you would round down because four is smaller than five or higher.) Since in your problem, you have 345,678, (we've already discussed the 14 million part in the beginning) 4 is smaller than 5 or higher so it would round 14,345,678 to 14,300,678. However, since we've already rounded the part we meant to do, every digit after would turn to 0. The final result would be 14,300,000.
Answer:
Cubic equations, which are polynomial equations of the third degree (meaning the highest power of the unknown is 3) can always be solved for their three solutions in terms of cube roots and square roots (although simpler expressions only in terms of square roots exist for all three solutions
