HELP PLEASE!!!!!! PLEASE!!!!

Nezavi [6.7K]

Answer:

x = 15°

Step-by-step explanation:

7x + 28° = 133° { being vertically opposite angles }

7x = 133° - 28°

7x = 105°

x = 105° / 7

x = 15°

< WPZ = 133° {being vertically opposite angles }

< WPZ = 7x + 28° = 7 * 15 + 28° = 133°

Hope it will help :)❤

Answer:

$\boxed{\sf{14}}$

Step-by-step explanation:

$\boxed{\underline{\text{ORDER OF OPERATIONS:}}}$

Use the order of operations.

Note: PEMDAS or BODMAS stands for:

PEMDAS

Parentheses
Exponents
Multiply
Divide
Add
Subtract

BODMAS

Brackets
Order
Divide
Add
Subtract

First, do parentheses.

3+6*(5+4)÷3-7

(5+4)=9

$\Longrightarrow: \sf{3+6* 9\div 3-7}$

Do multiply and divide.

6*9=54

54/3=18

Then, rewrite the problem down.

$\Longrightarrow: \sf{3+18-7}$

Add.

$\sf{3+18=21}$

$\sf{21-7=\boxed{\sf{14}}$

$\Longrightarrow: \boxed{\sf{14}}$

Therefore, the correct answer is "C. 14".

I hope this helps, let me know if you have any questions.

NISA [10]

Answer:

Building is 56.58 feet long.

Step-by-step explanation:

Consider the provided information.

An aerial photograph from a U-2 spy plane is taken of a building suspected of housing nuclear warheads.

When the photograph is taken, the angle of elevation of the sun is 30°.

By comparing the shadow cast by the building in question to the shadows of other objects of known size in the photograph, scientists determine that the shadow of the building in question is 98 feet long.

As we know: $\tan\theta=\frac{opp}{adj}$

The value of tan 30 degrees is $\frac{1}{\sqrt{3} }$

$\tan30=\frac{h}{98}$

$\frac{1}{\sqrt{3}}=\frac{h}{98}$

$h=\frac{98}{\sqrt{3}}$

$h=56.58$

Hence, Building is 56.58 feet long.
