If angle A =90 degree , b=1 cm and a =2 cm then solve the following right angled triangle ABC ​
Kruka [31]

Answer:

  • Angle A = 90 degrees, side a = 2.
  • Angle B = 30 degrees, side b = 1.
  • Angle C = 60 degrees, side c = \sqrt{3}.

Side c:

  • If angle A is 90 degrees, side a is the hypotenuse.
  • c^{2} + b^{2} = a^{2} <--- <em>this is NOT the correct way to write the Pythagorean theorem. I changed it to fit the side lengths. Normally, it is </em>a^{2} + b^{2} = c^{2}<em>, where c is the hypotenuse. Since a is the hypotenuse, I switched the variables.</em>
  • c^{2} + (1)^{2} = (2)^{2}
  • c^{2} + 1 = 4
  • c^{2} = 3
  • c = \sqrt{3}

Finding the angles:

  • <em>In a 30-60-90 right triangle, the...</em>
  • <em>Shortest leg = x</em>
  • <em>Longest leg = </em>x\sqrt{3}<em> </em>
  • <em>Hypotenuse = 2x </em>
  • In this case, the shortest leg is 1, the longer leg is \sqrt{3} (or 1*\sqrt{3}), and the hypotenuse is 2 (or 2*1).
  • As a result, this is a 30-60-90 triangle -- angle B is 30 degrees while angle C is 60 degrees.

Maria needs to buy cat food. At Save Rite, cat food costs $5.25 for 3 cans. Spend Less offers cat food at $7.50 for 5 cans. Mari
ozzi

Answer:

C

Step-by-step explanation:

First, in order to find the lowest price, you have to find the cost for 1 can in each store.

Save Rite: Since it is $ 5.25 for 3 cans, you divide 5.25 by 3. The quotient is 1.75. So, the price is $ 1.75 per can.

Then you do the same for Spend Less.

Spend Less: Since it is $ 7.50 for 5 cans, you divide 7.5 by 5. The quotient is 1.5. So, the price is $ 1.50 per can.

Since Save Rite's price for one can is $ 0.25 more than Spend Less, it is more expensive.  

So in order to see how much she paid for 15 cans from the cheapest store, you would have to multiply 15 by 1.5.

The answer is 22.50.

The answer is C

What is the missing coefficient of the x-term of the product (–x – 5)2 after it has been simplified?
valina [46]

we have

(-x-5)^{2}

we know that

(-x-5)^{2}=(-x-5)*(-x-5)

To multiply two binomial I can use the FOIL method

(-x-5)*(-x-5) =(-x)*(-x)+(-x)*(-5)+(-5)*(-x)+(-5)*(-5)\\ =x^{2} +5x+5x+25\\ =x^{2} +10x+25

therefore

the answer is

the missing coefficient of the x-term is 10
