When a triangle has angles 30°, 60°, and 90°, its side lengths are related to each other by a special ratio.

This ratio is such that the side opposite the 30°-angle is 1, the hypotenuse is 2, and the side opposite the 60°-angle is √3. This gives a ratio 1:2:√3.

Now, if we put in 7 for the side length opposite the 30°-angle, then the hypotenuse y must be 2 · 7, or 14, and the unknown leg x must be 7√3.

In sum: x=7 \sqrt{3}, y=14.

A store was keeping track of how many bottles of hand sanitizer and soap bars were sold last week. A bottle of hand sanitizer co
agasfer [191]

Answer:

Hand sanitizer=135 bottles

Bar soap=83 bottles

Step-by-step explanation:

Let x represent the hand sanitizer and y the sop.

-Our problem can be expressed as:

x+y=218\ \ \ \ \  ...i\\\\4.25x+2.15y=752.20\ \ \ \ \  ...ii

#Make x the subject in i then substitute in ii to solve;

x=218-y\\\\\therefore 4.25(218-y)+2.15y=752.20\\\\926.5-4.25y+2.15y=752.20\\\\174.3=2.1y\\\\y=83\\\\x=218-83=135

Hence, 135 bottles of hand sanitizer and 83 bottles of bar soap were sold.

What is the measure of angle VYZ
irakobra [83]

Answer:

\boxed{\sf C. \ 161 ^{ \circ}}

Step-by-step explanation:

<em>Opposite angles are also congruent angles, meaning they are equal or have the same measurement.</em>

\sf \implies \angle VYZ = \angle WYT \\  \\  \sf \implies(8x  + 1) ^{ \circ}  = (9x  - 19)^{ \circ}  \\  \\  \sf \implies 8x^{ \circ}  + 1^{ \circ}  = 9x^{ \circ}  - 19^{ \circ}  \\  \\  \sf \implies 8x^{ \circ}  - 9x^{ \circ}   + 1^{ \circ} =  - 19^{ \circ}  \\  \\  \sf \implies  - x^{ \circ}   =  - 19^{ \circ}   -   1^{ \circ}  \\  \\  \sf \implies  \cancel{ -} x^{ \circ}   =   \cancel{- }20^{ \circ}    \\  \\  \sf \implies   x^{ \circ}   =  20^{ \circ}

\therefore

\sf \implies \angle VYZ =(8x + 1) ^{ \circ}  \\  \\  \sf \implies \angle VYZ =(8  \times 20 + 1) ^{ \circ}  \\  \\  \sf \implies \angle VYZ =( 160+ 1) ^{ \circ}  \\  \\  \sf \implies \angle VYZ =161 ^{ \circ}

Can someone please help me on this??
Usimov [2.4K]

Answer:

C

Step-by-step explanation:

To solve this use the equation x^2 -15x - 50 = y given in the problem and the value y = 50. Substitute y = 50 then solve for x by factoring.

x^2 -15x - 50 = 50\\x^2 - 15x -100 = 0

Find two numbers which multiply to -100 and also add to -15. The numbers are -20 and 5.

So the factored form is (x-20)(x+5) = 0.

Set each factor equal to 0 and solve.

(x-20) = 0 so x = 20.

(x+5)=0 so x = -5.

This means the temperature is 20 degrees C or -5 degrees C. Only 20 is an option. The solutions is C.
