Answer:
∠A=67°
∠B=70°
∠C=43°
Step-by-step explanation:
<u><em>The correct question in English is</em></u>
Determines the measurement of each of the angles of the triangle ABC if it is known that A=(3x+1)°,B=(3x+4)° and C=(2x-1)°.
we know that
The measure of the interior angles in a triangle must be equal to 180 degrees
so
∠A+∠B+∠C=180°
substitute the given values
solve for x
Find the measure of each angle
∠A=(3(22)+1)=67°
∠B=(3(22)+4)=70°
∠C=(2(22)-1)=43°
Answer:
30 leaps
Step-by-step explanation:
Equation of rabbit:
y=7x+150
Equation of kangaroo:
y=12x
To solve the system of equations, use substitution
12x=7x+150
5x=150
x=30

The amount of passwords you can guess are 4,569,760.
How this is found is by multiplying the amount of numbers in the alphabet by itself 4 times, then multiplying by the amount of 1 digit numbers there are, so multiply by 10, it is ten because you can have the number as 1 2 3 4 5 6 7 8 9 or 0, and then the number you get is your answer. Hope this helped! ^_^
Answer:m(.70)+80(.25)=.6(m+80)
.7m+20=.6m+48
.1m=28
m=28/.1=280 gallons of 25% antifreeze needed
