Answer:
Step-by-step explanation:
we know that
In the right triangle of the figure
The cosine of angle A is equal to divide the adjacent side to angle A by the hypotenuse
so
----> by CAH
Find the measure of the angle A
Answer:
x = 33
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
x+114+33 = 180
Combine like terms
x+147 = 180
Subtract 147 from each side
x+147-157 = 180-147
x = 33
R+3>7
-3 -3
r>4
just write it right I couldn't find the same sign
Answer:
24
Step-by-step explanation:
First we do order of operations. So we answer the problems on the left side first. So we do (-2) * (+3) which equals (-6). Then we do (-6) * (-4) which equals (+24).
Answer:
Look for bolded sentences
Step-by-step explanation:
1. Let n be the first number. The second number would be n+5. Now let's write an equation...
n+n+5=17
2n+5=17
2n=12
n=6
n+5=11
The numbers are 6 and 11
2. Let n be the first number. The second number would be n+12...
n+n+12=60
2n+12=60
2n=48
n=24
n+12=36
The numbers are 24 and 36
3. Let n be the number of boys. The number of girls is n+36...
n+n+36=812
2n+36=812
2n=776
n=388
n+36=424
424 girls attend the school
4. Let the amount of money Stan has be n. Then Cory has 2n+24...
n+2n+24=132
3n+24=132
3n=108
n=36
2n+24=2(36)+24=72+24=96
Stan has $36 and Cory has $96
