Find the values of the sine, cosine, and tangent for ZA. (TOP OF TRIANGLE IS (A))

Sloan [31]

$\bigstar\:{\underline{\sf{In\:right\:angled\:triangle\:ABC\::}}}\\\\$

AC = 7 m
BC = 4 m

⠀⠀⠀

$\bf{\dag}\:{\underline{\frak{By\:using\:Pythagoras\: Theorem,}}}\\\\$

$\star\:{\underline{\boxed{\frak{\purple{(Hypotenus)^2 = (Perpendicular)^2 + (Base)^2}}}}}\\\\\\ :\implies\sf (AB)^2 = (AC)^2 + (BC)^2\\\\\\ :\implies\sf (AB)^2 = (AB)^2 = (7)^2 = (4)^2\\\\\\ :\implies\sf (AB)^2 = 49 + 16\\\\\\ :\implies\sf (AB)^2 = 65\\\\\\ :\implies{\underline{\boxed{\pmb{\frak{AB = \sqrt{65}}}}}}\:\bigstar\\\\$

⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━

☆ Now Let's find value of sin A, cos A and tan A,

⠀⠀⠀

sin A = Perpendicular/Hypotenus = $\sf \dfrac{4}{\sqrt{65}} \times \dfrac{\sqrt{65}}{\sqrt{65}} = \pink{\dfrac{4 \sqrt{65}}{65}}$

⠀⠀⠀

cos A = Base/Hypotenus = $\sf \dfrac{7}{\sqrt{65}} \times \dfrac{\sqrt{65}}{\sqrt{65}} = \pink{\dfrac{7 \sqrt{65}}{65}}$

⠀⠀⠀

tan A = Perpendicular/Base = ${\sf{\pink{\dfrac{4}{7}}}}$

⠀⠀⠀

$\therefore\:{\underline{\sf{Hence,\: {\pmb{Option\:A)}}\:{\sf{is\:correct}}.}}}$

If a bucket holds 2 2/4 gallons of water. And the bucket is 5/8 full. how full is the bucket

s344n2d4d5 [400]

Multiply 2 2/4 by 5/8.

First, simplify 2 2/4 to 2 1/2.

Then, convert to improper form (5/2).

5/2 x 5/8 = 25/16

answer: 1 9/16 gallons of water

Hillary needs a few new items for the start of softball season. She found some great sales! Help her find out the price she will

kolezko [41]

Answer:Hillary will pay $35.00 for softball glove, $20.00 for soft ball bat and $40.00 for cleats

Step-by-step explanation:

Step 1

A percentage off of a price of an item is the amount that can be saved from purchasing that item, it can also be referred as a discount given on an item purchase.

Step 2 --- Calculation

Actual Price of Softball glove= $50

Discount= 50 x 30/100 = $15.00

Price to pay= $50 - $15.00 = $35.00

Actual Price of soft ball bat= $50

Discount= 50 x 60/100 = $30.00

Price to pay= $50 - $30.00 = $20.00

Actual Price of cleats= $50

Discount= 50 x 20/100 = $10.00

Price to pay= $50 - $10.00 = $40.00

Therefore, Hillary will pay $35.00 for softball glove, $20.00 for soft ball bat and $40.00 for cleats
