The three angles of a triangle are in the ratio of 2:3:5. calculate the size of the biggest angle.​
Inessa05 [86]

Answer:

80°

Step-by-step explanation:

The sum of the angles of a triangle is always 180°.

∴ 2x + 3x + 5x = 180°

                  10x = 180°

                     x = 180 / 10

                     x = 18

The biggest angle = 5x

                              = 5 * 18

                              = 90°

If x^y = z is there any way to find y if you know x and z?
Rzqust [24]

We make use of y = \log_x(z) to solve for y, when you know x and z

<h3>How to solve for y?</h3>

The expression is given as:

x^y = z

The above expression is an exponential expression.

Start by taking the logarithm of both sides

y log(x) = log(z)

Divide both sides by log(x)

y = \log_x(z)

Hence, we make use of y = \log_x(z) to solve for y, when you know x and z
