Answer:
x=3.5
Step-by-step explanation:
x×6=3×7
x=21/6=7/2=3.5
Multiplying decimals:
First, multiply like a normal number.
64 × 37 = 2368
Add up the number of decimal points from your original numbers to find out where you should put the decimal point on your result.
6.4 has one decimal place, and -3.7 has one decimal place.
Our result should have two decimal places. (1+1)
23.68
Because we multiplied by a negative number, our result should be negative, too.
-23.68
Answer:
Proved CA=CB
Step-by-step explanation:
Given,
In ΔABC, CP is perpendicular to AB.
And CP bisects AB.
So, AP=PB and ∠CPA=∠CPB=90°
The figure of the triangle is in the attachment.
Now, In ΔACP and ΔBCP.
AP = PB(given)
∠CPA = ∠CPB = 90°(perpendicular)
CP = CP(common)
So, By Side-Angle-Side congruence property;
ΔACP ≅ ΔBCP
According to the property of congruence;
"If two triangles are congruent to each other then their corresponding sides are also equal."
Therefore, CA = CB (corresponding side of congruent triangle)
CA = CB Hence Proved
