Answer:
w=4
Step-by-step explanation:
so assuming that that is a plus sign instead of an equal sign it would be 4
Answer:
151 degrees
Step-by-step explanation:
This triangle has supplementary angles, so we need the triangle to add up to 180 degrees.
Start off with 61 degrees, below the 61 degrees symbol, there is a right angle under it, a right angle equals to 90 degrees. Then subtract 90 from 61, so the last angle is 29 degrees.
Then subtract 180 from 29, then your answer is 151 degrees.
Answer: 3
Step-by-step explanation: [ 3.6 ] represents the greatest integer function [ x ]
If x is an integer use that integer
If x is not an integer use the next smaller integer
[ 3.6 ] is not an integer, hence
[ 3.6 ] = 3
Answer:
Step-by-step explanation:
Let the coordinates of point B are (x, y).
Since the rotation is clockwise the angle measure between OA and OB is -60° (IV quadrant).
- x = 15 cos (-60°) = 7.5
- y = 15 sin (-60°) = -12.99
<u>The distance between A and B is:</u>
- AB = = 15 units
<h3><u>Another solution</u></h3>
Since OA = OB = 15 units and AOB is 60° angle the triangle OAB is equilateral. Hence AB is same as OA and OB, so AB = 15 units.
