Step-by-step explanation:

all sides of a triangle = 180

So 2 angle i.e. 90° (right angle) and 30° (given) and let third angle be x

so equation forms like

180 = 90+30+x

180 =120+x

180-120 =x

60 =x

SO THE ANSWER WILL BE 60°

HOPE IT WILL HELP YOU ☺️

Write the quadratic equation whose roots are 3 and -1, and whose leading coefficient is 5.

Assoli18 [71]

Answer:

5x² - 10x - 15 = 0

Step-by-step explanation:

Given that the roots are x = 3 and x = - 1, then the factors are

(x - 3) and (x + 1) and the quadratic is the product of the factors, that is

f(x) = a(x - 3)(x + 1) ← a is a multiplier

Here a = 5, thus

f(x) = 5(x - 3)(x + 1) ← expand factors using FOIL

= 5(x² - 2x - 3) ← distribute parenthesis by 5

= 5x² - 10x - 15

Thus equation is

5x² - 10x - 15 = 0

A realtor sold a home for $341,100 The commission was 4% of the sale price; however, the realtor receives only 60% of the com

Pepsi [2]

Answer:

The relator recived $8,186.4

Step-by-step explanation:

What you have to do is find the 60% of the commission. Commission is 4% of $341,100 (100%)

First do a cross multiplication to find 4% of $341,100

100% ___ $341,100

4%______x:

$x=(4*341,100)/100=13,644$

So, the 4% of $341,100 is $13,466

Now you have to find the 60% of $13,466

100% ___ $13,466

60%______x:

$x=(60*13,466)/100=8,186.4$

The answer is: $8,186.4

Solve for x in the diagram below.

Ghella [55]

Answer:

x= 20

Step-by-step explanation:

The three angles add to 90 degrees

x+2x+x+10 = 90

Combine like terms

4x+10 = 90

Subtract 10 from each side

4x +10-10 = 90-10

4x = 80

Divide by 4

4x/4 = 80/4

x = 20
