Answer:
486
Step-by-step explanation:
if you mean 485.782 with a decimal then it would be 486
Well, the interseciton of 2 planes would be a line, so it would be like line AB when it goes through the 2 points A and B
Divide it into two squares.
The first square is just (1)1, which equals 1 cm^2, and add that to the second square, which is just (2)2, which equals 4, so 1+4=5 cm^2.
4 is the correct answer i believe! :) sorry if wrong.
please put brainliest!
Answer:
m<ACD = 
Step-by-step explanation:
From the question given, ΔACD is a right angled triangle. Then we can apply one of the properties of a triangle to it.
In the triangle ACD:
<ACD + <DAC + <ADC = 180 (sum of angles in a triangle)
<ACD + 40 + 90 = 180
<ACD + 130 = 180
<ACD = 180 - 130
<ACD = 
With the application of the property of the sum of interior angles of a triangle, the measure of <ACD is
.
