Answer:
x = y = 15
Step-by-step explanation:
Using the sine ratio and the exact value
sin45° = , then
sin45° = =
=
( cross- multiply )
2x = 30 ( divide both sides by 2 )
x = 15
The triangle is isosceles (45- 45- 90) , then 2 legs are congruent, so
y = x = 15
Answer:
y=-11
Step-by-step explanation:
A line can be represented by a linear equation of
where m is the slope and y is the y intercept.
The slope is 0 so this function will be
Which is also called a constant function. The y intercept is -11. So the answer is
Answer:
x = 6

Step-by-step explanation:
Logarithms are just another way to write exponents. The base on the logarithm that is the small font subscript IS the base (normal font/on the line) of an exponential equation. The "answer" in the logarithmic equation is the exponent (small font/superscript) .It is just a triple shuffle. When the logarithmic equation cant be worked on to solve it, CHANGE IT to exponential form. See image.
