Can someone please help me :)

Mathematics
1 answer:
gavmur [86]3 years ago
7 0

Answer:

<em>90 degree</em>

Step-by-step explanation:

Three points A, B, and C are added and shown in attached picture.

As the property of inscribed angle in circle:

angle BAC = (1/2) x 88 = 44 deg

As the property of complement angle:

angle ABC = 180 - 89 = 91 deg

As the property of sum of three angles in a triangle:

angle ACB + angle ABC + angle BAC = 180 deg

=> angle ACB = 180 - angle ABC - angle BAC = 180 - 44 - 91 = 45 deg

One more time, we use the property of inscribed angle in circle:

x = 2 x angle ACB = 2 x 45 = 90 deg

Hope this helps!

Emir is standing in a treehouse and looking down at a swingset in the yard next door. The angle of depression from Emir's eyelin
boyakko [2]
<h3>Answer:  24 feet  (Choice D)</h3>

=============================================

Explanation:

Refer to the diagram below. The goal is to find x, which is the horizontal distance from the base of the tree to the swing set.

Focus on triangle BCD.

The angle B is roughly 30.26 degrees, and this is the angle of depression. This is the amount of degrees Emir must look down (when starting at the horizontal) to spot the swing set.

We know that he's 14 ft off the ground, which explains why AB = CD = 14.

The goal is to find BC = AD = x.

---------------------------

Again, keep your focus on triangle BCD.

We'll use the tangent ratio to say

tan(angle) = opposite/adjacent

tan(B) = CD/BC

tan(30.26) = 14/x

x*tan(30.26) = 14

x = 14/tan(30.26)

x = 23.9965714046732

That value is approximate. Make sure your calculator is in degree mode.

That value rounds to 24 feet when rounding to the nearest whole foot.

-Dominant- [34]

Answer:

The second choice (7.6,8.8)

Step-by-step explanation:

The missing image is attached

We use the section formula:

(x,y)=(\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n})

We substitute x_1=3,x_2=16,y_1=2,y_2=21 and m=5, n=9

(x,y)=(\frac{5*16+9*3}{5+9},\frac{5*21+5*2}{9+5})

We simplify to get:

(x,y)=(\frac{80+27}{14},\frac{105+10}{14})

This simplifies to:

(x,y)=(\frac{107}{14},\frac{125}{14})

In decimals we get:

(x,y)=(7.6,8.8)

Convert the following percent into common fractions in simplest form:<br> 5 1/3%
Tomtit [17]

Answer:

4/75

Step-by-step explanation:

you will get 5 and 1/3 percent equals (5 + 1/3) / 100 which is equal to 5/100 + (1/3) / 100 which is equal to 5/100 + 1/300. place both fractions under a common denominator. you will get 5/100 + 1/300 = 15/300 + 1/300 = 16/300. simplify the fraction to get 16/300 = 8/150 = 4/75

In her first five basketball games, Tara scored 10, 11, 15, 16, and 18 points. What is the mean absolute deviation for this set
Daniel [21]
Hello there, and thank you for posting your question here on brainly.

To find mean absolute deviation, (MAD) you have to add all the numbers together, and then divide by how much numbers are in the set.

So we have to do 10 + 11 + 15 + 16 + 18, and then divide by 5.

10 + 11 + 15 + 16 + 18 ===> 70

Now, divide by 5.

70 / 5 ===> 14

The mean absolute deviation is 14.

Hope this helped! ☺♥
