So the equation of the angles add to the measure of a straight angle is Then we need to find the measure of â QST and â RST.Īs we have plotted a straight line which is date 2012 Topics Mathematics - Study and teaching (Secondary), Mathematics - Study and teaching - Problems, exercises, etc, Mathematics - Study and teaching Publisher Calgary, Alberta. Write an equation to show that the angles add to the measure of a straight angle. iWrite math foundations of mathematics book 12 by Appleby, Alan, author. Plot a point O somewhere between points M and N.į. So the equation will be 90°= 27°+x° and the value of x isĬomplete the following directions in the space to the right.Ī. Here, in the above image we can see that a rectangle where every angle is a right angle, so letâs take one angle as 90° and then we should find out the other angle and the other angle be x. Write an equation that could be used to solve the problem. Without using a protractor, determine the measurement of â DEB. In the following figure, ACDE ¡s a rectangle. Given that This app offers a rich user interface with writing, drawing highlighting and even an. Given that that which is 90° and another angle is 20°, so the angle GFE= 90° which is 20°+x= 90°, so the value of x is x°= 90° â 20° Given that
