Answer:
yes the two triangles are similar
Answer:
32
Step-by-step explanation:
If you divide 7200 by 64 you get 112.5 or 112 large boxes. If you do 112*64 you get 7168. Subtract 7168 by 7200 and you get 32
Answer:
x=18, m∠1=140, m∠2=40
Step-by-step explanation:
m∠1 and m∠2 will equal up to 180
7x+14+2x+4=180
Combine like-terms
9x+18=180
Subtract 18 from both sides.
9x=162
Divide both sides by 9
x=18
Then plug in 18 for x in the angle measures
7(18)+14=140
2(18)+4=40
Answer:
raju is 20 years old while the father is 40 years old
Step-by-step explanation:
present : lets assume raju is x years old so the father will be 2x
after 10 yrs raju will be x+10 yrs while the father will be 2x+10 yrs
therefore :
(x+10)+(2x+10)=80
liketerms together
x+2x+10+10=80
3x+20=80
3x=80-20
3x=60
simplify
x=20 so raju is 20 years old now and the father since he is twice the age of his son he is 40 years old
Answer:
Equal sides = 6cm each
Unequal side = 12cm
Step-by-step explanation:
Perimeter of a triangle = side a + side b + side c
Let
Side a = side b = x
Side c = 2x
Perimeter of the triangle=24cm
Perimeter of a triangle = side a + side b + side c
24 = x + x + 2x
24 = 4x
Divide both sides by 4
24 / 4 = 4x / 4
6 = x
x = 6
The equal sides = x = 6cm each
The unequal side = 2x
= 2(6)
= 12cm
Check:
Perimeter of a triangle = side a + side b + side c
= 6cm + 6cm + 12cm
= 24cm
