Answer:

  x = 2√2 ≈ 2.83

Step-by-step explanation:

The side length of an isosceles right triangle is 1/√2 times the hypotenuse length. If x is the side length, then ...

  x = 4/√2 = 4(√2)/2

  x = 2√2 ≈ 2.83

__

You have not specified the form of the answer. Sometimes an exact answer (2√2) is required. Sometimes the answer is required to be rounded to tenths or hundredths.

Reil [10]

Answer:

G, the second option

Step-by-step explanation:

A triangle's degrees all adds up to 180.

45 + 60= 105 degrees

180-105= 75 degrees

<u>that in which makes </u><u>z=75 degrees.</u>

Since z is sharing a straight angle, which is 180 degrees

180-75= 105 degrees.

<u>Therefore, </u><u>w=105 degrees</u>

Write an equation of each line with the given slope and y-intercept. slope =1/2 ; y-intercept = 0
CaHeK987 [17]

Answer:

y=1/2x

Step-by-step explanation:

Equations of lines are written in slope-intercept form:

y=mx+b

where m is the slope and b is the y intercept.

The slope is 1/2 and the y-intercept is 0. Therefore, we can substitute 1/2 for m and 0 for b.

y=1/2x+0

Adding 0 onto the end doesn't change the equation and doesn't serve a purpose, so it can be removed from the end of the equation.

y=1/2x

The equation is: y=1/2x

21 and 22 are complementary angles. The measure of Z1 is 60°. The
Lemur [1.5K]

Answer:

The value of x is 7

Step-by-step explanation:

Complementary angles have a sum of 90°, therefore the equation to solve for x is:

∠1+∠2=90°

60°+5(x-1)°=90°

5(x-1)=30°

x-1=6

x=7

So the value of x is 7
