Answer:

9.83cm

Step-by-step explanation:

Since we are not asked what to look for. We can find the height of the wall.

Let the height of the wall be H

Given

Length of the ladder l = 12fot

Angle of elevation = 55degrees

Required

Height of wall H

Using the SOH CAH TOA identity

SIn theta = opp/hyp

Sin 55 = H/12

H - 12sin55

H = 12(0.8192)

H = 9.83cm

Hence the height of the ladder is 9.83cm

The longest side of an acute triangle measures 30 inches. The two remaining sides are congruent, but their length is unknown.
Leno4ka [110]
Really, we don't need to use that much math--we can use logic instead. Since the two congruent sides must be longer than 30in, the total has to be greater than 60in (the longest side plus the congruent sides.) So for our answer, we want the smallest total that is above sixty, which in this case is 72.44in.

Hope I helped, and let me know if you have any questions :) I can explain the real math if you want, it was just unnecessary here.

PLZ HELP! Lenny is 3 times older than Max. When you subtract Max’s age from Lenny’s age, you get 24. How old is Lenny and how ol
tresset_1 [31]
Hi!

(l = Lenny
m = Max)

Lenny is 3 times as old as Max.
3m = l

When you subtract Max's age from Lenny's age, you get 24.
L - m = 24

Put in the value of l.
3m - m = 24
There is our equation.

Now solve

2m = 24
2m/2 = 24/2
m = 12

3 * 12 = l
36 = l

The equation is 3m - m = 24
Max is 12 and Lenny is 36.

Hope this helps! :)

Hey math can you help
HACTEHA [7]
So if we’re talking about meters per second, you would need to divide.

-17.5/5 = -3.5

NOW YOU THINK THATS YOUR ANSWER BUT NOO. You CANNOT have a negative second. So you take the absolute value of -3.5 and your answer would be 3.5

The rate of the anchor is 3.5 meters per second.
