Help me with this geometry

Mathematics
1 answer:
KiRa [710]3 years ago
6 0

Answer:

x= (5X+3) DEGREES = 90 degrees (right angle)

5x=90 degrees - 3 degrees =87 degrees

5x÷5 =87 degrees ÷ 5

x=17.4 degrees

we now know our angles x = 17.4 degrees so we can know substitute into the give formula

wxz=5 (17.4)+ 3

wxz =90 degrees

zxy=we know the size of x

zxy=

8 (17.4)-4

zxy=135.2 degrees

How is 225 divisible by nine
Ivanshal [37]
A number is divisible by 9 if and only if the sum of its number is a multiple of nine.

2+2+5=9 hence 255 is divisible by 9.

What's the answer to this
timofeeve [1]

Answer:

AC ≈ 17.3 , BC ≈ 5.3

Step-by-step explanation:

using the tangent ratio in right triangle ACD

tan51° = \frac{opposite}{adjacent} = \frac{AC}{AD} = \frac{AC}{14} ( multiply both sides by 14 )

14 × tan51° = AC , then

AC ≈ 17.3 ( to the nearest tenth )

using the cosine ratio in right triangle ABC

cos72° = \frac{adjacent}{hypotenuse} = \frac{BC}{AC} = \frac{BC}{17.3} ( multiply both sides by 17.3 )

17.3 × cos72° = BC , then

BC ≈ 5.3 ( to the nearest tenth )

No one helps me please help
Ksenya-84 [330]

Answer:

A, C, and D

Explanation:

32 rows

15 seats per 1 row

So,

32 × 15 = k

You can try arranging to get more choices.

32 × 15 = k

32 = k ÷ 15

and

32 × 15 = k

15 × 32 = k

15 = k ÷ 32
