A certain triangle has two 45° angles, what thoe of triangle is it?

1 answer:

7 0

Add the two known angles: 45° + 45° = 90°

Now we know the third angles. Which is a 90 degree angle. If a triangle has a 90 degree angle, then it is a right angle triangle.

The difference of two numbers is 19. The larger number is three more than twice the smaller. Find the numbers.

iren [92.7K]

Let x=the larger number
y=the smaller number
If the difference of two numbers is 19,then
$x - y = 19$
If the larger number is 3 more than twice the smaller,
$x = 2y + 3$
subsituting
$x = 2y + 3 \: to \: x - y = 19$
$2y + 3 - y = 19 \\ 2y - y + 3 = 19 \\ y + 3 = 19 \\ y + 3 - 3 = 19 - 3 \\ y + 0 = 16$
$y = 16$
but ×=2y+3 so,
$x = 2 (16) + 3 \\ x = 32 + 3 \\ x = 35$
Therefore, the two numbers are 16 and 35.

What does the equation y=mx+b mean? Hey new to brainly and looking for people to chat with.

Anastaziya [24]

Answer: it is slope intercept form

Example: y= 5x + 8

this means that 5x is the slope so when graphed, you would go 5 up and 1 over (you can think of it as 5/1) and the 8 signifies the y- intercept. The y- intercept indicates where you start graphing
