Answer:
D) 5
Step-by-step explanation:
The smaller triangle is similar to the big triangle with the big triangle with a scale factor of 1.8.
5x × 1.8 = 45
<em>Divide both sides by 1.8</em>
5x = 25
<em>Divide both sides by 5</em>
x = 5
If you would like to know what is the answer for 6 - 7/8, you can calculate this using the following steps:
6 - 7/8 = 48/8 - 7/8 = (48 - 7) / 8 = 41/8 = 5 1/8 = 5.125
The correct result would be 41/8 or 5 1/8.
A is correct:
m∠ABD=1/2(mCD-mAC)
m∠ABD=1/2(132-72)
m∠ABD=1/2(60)=30
Answer:
The error is:
He multiplied the dividend by 100 instead of 10
Step-by-step explanation:
∵ 1.926 ÷ 0.9 ⇒ means
1.926 = 1926/1000 ⇒ dividend
0.9 = 9/10 ⇒ divisor

∵ 1926/100 = 19.26 ⇒ dividend
∴ 19.26 ÷ 9 = 1926/100 ÷ 9
19 ÷ 9 = 2 with remainder 1/9
12 ÷ 9 = 1 with remainder 3/9
36 ÷ 9 = 4 no remainder
∴ The quotient is 214/100 = 2.14
C. <2 and <6 is the answer
