Find the value of x in the isoscleles triangle sqrt45 and altitude 3​

Mathematics
1 answer:
Alisiya [41]3 years ago
8 0

Answer:

c.\hspace{3}x=12

Step-by-step explanation:

Isosceles triangles are a type of triangles in which two of their sides have an identical length. It should be noted that the angles opposite the sides that are the same length are also the same. This means that these triangles not only have two equal sides, but also two equal angles.

You can solve this problem using different methods, I will use pythagorean theorem. First take a look at the picture I attached.  As you can see:

x=2a

And we can find a easily using pythagorean theorem:

(\sqrt{45} )^{2} =3^{2} +a^{2}

Solving for a:

a^{2} =(\sqrt{45} )^{2} -3^{2} \\\\a^{2} =45-9\\\\

a^{2} =36\\\\a=\sqrt{36} \\\\a=6

Therefore:

x=2a\\\\x=2(6)\\\\x=12

Write an exponential function in the form y = ab that goes through points (0,4)<br> and (2, 196).
yawa3891 [41]

Answer:

y = 4(7)^{x}

Step-by-step explanation:

The form of the exponential function is y = a b^{x}

Use the given points to solve for a and b

Using (0, 4 ), then

4 = ab^{0} ( b^{0} = 1 ), thus a = 4

y = 4 b^{x}

Using (2, 196 ), then

196 = 4b² ( divide both sides by 4 )

49 = b² ( take the square root of both sides )

b = \sqrt{49} = 7

y = 4(7)^{x} ← exponential function
