The triangle above is isosceles and b&gt; a. Which<br> of the following must be FALSE?
kow [346]

If the triangle is isosceles and b is greater than a then,

(c) AC = BC is false.

An isosceles triangle in geometry is one with at least two equal-length sides. It can be defined as having exactly two equal-length sides or as having at least two equal-length sides, with the equilateral triangle being an exception to the second definition.

The triangle is an isosceles triangle and angle b is greater than angle b.

For option (A),

AB = BC, therefore a = c which is possible.

For option (B),

AB = AC, therefore b = c which is also possible.

For option (C),

AC = BC, therefore a =b.

But we have b > a. Hence AB  = BC is false.

For option (D),

a = c, therefore AB = BC which is possible according to the properties of an isosceles triangle.

Option (C) is false.

A rectangle with area 36 square inches has a length that is 3 less than 3 times the width. Find the length and the width of the
OlgaM077 [116]

Answer:

length = 9 in ; width = 4 in

Step-by-step explanation:

1) formula of the area of a rectangle

A = base x width

2) write an equation with the given informations:

w x (3w-3) = 36

3) solve the equation

-  multiply W by 3w and -3

3w^2 -3w = 36

- divide the two members by 3

w^2 - w = 12

- add up -12 at the two members

w^2-w -12 = 12 -12

w^2 - w - 12 = 0

- find two numbers whose sum is -1 and whose product is -12 and factorise the equation

(w-4)(w+3) = 0

- find the two solutions

w-4 = 0

w = 4

w+3 = 0

w = -3

4)remember that a length can’t be negative.

w = 4 is the only solution

5) find the length

4x3 - 3 = 9

Please help!! I will mark the brainlest if it’s correct
strojnjashka [21]

Answer:

Therefore

m Angle 1 = m Angle 2  = 31° ...Justified

Step-by-step explanation:

Given:

m angle 1 = ( 3x + 10 )°

m angle 2 = ( 5x - 4 )°

To Find:

m∠1 = ?

m∠2 = ?

Solution:

Vertical Angles:  

The angles opposite each other when two lines cross. They are always equal.

∴ m Angle 1 = m Angle 2

Substituting the given values we get

3x+10=5x-4\\\\2x=14\\\\x=\dfrac{14}{2}=7\\\therefore x =7

Substituting ' x ' in Angle 1 and Angle 2 we get

m Angle 1 = 3 × 7 + 10 = 31°

m Angle 2 = 5 × 7 - 4  = 31°

Therefore

m Angle 1 = m Angle 2  = 31° ...Justified
