Hi there!

Let's start with finding the measurement of angle A. Looking at the image, we know that the larger, outer triangle is equilateral. Therefore, we know that the inner, smaller triangle is isosceles. So, to find the measure of angle A, we need to solve this here equation:

180 = 90 + 2A
90 = 2A
A = 45

Now that we know that angle A is equal to 45 degrees, we can take the total value of the angle of the equilateral triangle and subtract the value of angle A from it to find the value of angle B.

B = 60 - 45
B = 15 degrees

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

An airplane has begun its descent for a landing. When the airplane is 150 miles west of its destination, its altitude is 25,000
belka [17]
The airplane has descended (25,000 - 19,000) = 6,000 feet
while flying (150 - 90) = 60 miles.

If the descent is modeled by a linear function, then the slope
of the function is

             (-6000 ft) / (60 miles)  =  - 100 ft/mile .

Since it still has 19,000 ft left to descend, at the rate of 100 ft/mi,
it still needs to fly

           (19,000 ft) / (100 ft/mile) =  190 miles

to reach the ground.

It's located 90 miles west of the runway now.  So if it continues
on the same slope, it'll be 100 miles past the runway (east of it)
when it touches down.

I sure hope there's another airport there.

Write logbx + logby - logbz as a single logarithm.
IrinaK [193]
Logbx+logby-logbz
=logb(x*y)/z if b is the base of log.
There are two properties that you can apply to get the correct answer.
logb(x*y)=logbx+logby if b is the base of log.
logb(x/y)=logbx-logby if b is the base of log, so the correct answer for logbx+logby-logbz=logb(x*y)/z. Hope it help!

NEEEEEEEEEED ANSWER FFFFFFAAAAAAAAAAASSTTTTTTTT
Firdavs [7]
(y^2)^5 × y^8
Use the rule:
({ {y}^{m} })^{n}  =  {y}^{m \times n}
To get:
y^10, then, use the rule:
{y}^{m}  \times  {y}^{n}  =  {y}^{m + n}
To eventually get:
y^(10+8) = y^18 or: y18 seeing as you wrote it like that.
