Answer:
68°
Step-by-step explanation:
ABD is a right angle and the measure of it is 90°
m<CBD + m<ABC = m<ABD
4x + 52° + 8x - 10 = 90° add like terms
12x + 42° = 90°
12x = 48°
x = 4
m<CBD is 4x + 52° replace x with 4
4×4 + 52 = 68°
The answer is 1.869 or 1.87
Answer:
True: 1, 4, 5
Step-by-step explanation:
Main notations:
A plane is a flat 2D surface with no thickness that extends infinitely far. (Option 1 is true)
A point is an exact location. It has no size, no width, no length, no depth, only position. (Option 2 is false)
Collinear points are two or more points that lie on the same line and have different location. (Option 3 is false)
A line is straight (no bends), has no thickness, and extends in both directions without end (infinitely). (Option 4 is true)
The distance between two points is the length of a line segment that connects them. (Option 5 is true)
So you can choose any number from 11 to 19.
I'll choose 11 for now.
Then you write, 11, the number, and then spell it out, eleven.
To show how many tens and ones, you can make a place value chart. You would make two boxes, the first one for tens and the other for ones.
You would put a 1 in the tens place and a 1 in the ones place.
I hope this helps!
