Answer:

m<F=50

Step-by-step explanation:

complementary angles mean that together they equal 90, we need to set up an equation to find x, and then put x into angle F to find its measurement :)

m<C+m<F=90

(2x+10)+(x+35)=90

calculate to find x!

x=15

now we put 15 into (x+35)

15+35=50

kirill115 [55]

Answer:

(-1,-1)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2

(1+-3)/2 = -2/2 = -1

To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2

(-6+4)/2 = -2/2 = -1

(-1,-1)

Write an expression that can be used in over a temperature from degrees Celsius see to degrees Fahrenheit and then use the expre
densk [106]

Answer:

25°C = 77 degree Fahrenheit.

Step-by-step explanation:

In this question we have to write the expression showing the relation between degree Celsius and degree Fahrenheit first.

C=\frac{5}{9}(F-32)  where C = degree centigrade and F = degree Fahrenheit

Although the question is not clear in the next part but assuming that we have to use this expression to convert 25°C to degree Fahrenheit,

We will plug in the value of C in the expression,

25=\frac{5}{9}(F-32)

F=(\frac{9}{5}\times 25)+32

F = 45 + 32

F = 77

Therefore, 25°C = 77 degree Fahrenheit will be the answer.
