If Alberto's school is 3 miles due south of his house and 4 miles due west of Jimmy's house, what is the straight line distance
Hoochie [10]

using the Pythagorean Thereom:

3^2 +4^2 = X^2

9 +16 = 25

x^2 = 25

X = sqrt (25)

x = 5

 it would be 5 miles

What is the nearest perimeter of rectangle ABCD, to the nearest tenth?
Snowcat [4.5K]

Answer:  B

Step-by-step explanation:

Perimeter = 2(length+width)

 'CD' = 20×cos(30) = 17.3205

width 'AD' = 20×cos(60) = 10

Perimeter = 2(17.3205+10)

= 2(27.3205)

= 54.641 =54.6

Please help me last question
Alborosie

As you can see there are two triangles but it can be done calculating just for one. First we must understand how formula for area of triangle works.

A=\frac{1}{2}bh

Where b represents base (hypotenuse) and h as height of the triangle.

We know that:

b=13cm \\h=4cm

Using this data we fill the formula.

A=\frac{1}{2}\cdot13\cdot4=\frac{13\cdot4}{2}=13\cdot2=\boxed{26cm^2}

Hope this helps.

Please help me really quick pleasee<br> answer choices:<br> a)2<br> b)11<br> c)20<br> d)29
mihalych1998 [28]

Answer:

C. x=20^{\circ}

Step-by-step explanation:

Angle 6 and angle with measure 45° are vertical angles (opposite angles whan two lines intersect). By Vertical Angles Theorem, vertical angles are congruent, so

m\angle 6=45^{\circ}

Angle 6 and angle with measure 5x+35^{\circ} are the same side interior angles when two parallel lines are cut by transversal. The same side interior angles add up to 180°, then

m\angle 6+5x+35^{\circ}=180^{\circ}\\ \\45^{\circ}+5x+35^{\circ}=180^{\circ}\\ \\5x=180^{\circ}-45^{\circ}-35^{\circ}\\ \\5x=100^{\circ}\\ \\x=20^{\circ}
