Answer:We solve m equations ar b in 1 Un known (by least squares). (a) Solve aTa± = aTb to show that § is the mean (the average) of the b’s.
Step-by-step explanation:
I guess you want the measure of angle <CAB.
The angle ABD is flat thus its amplitude is 180 degrees. Because
<ABD = <ABC + <CBD you get
<ABC = <ABD - <CBD = 180° - 122° = 58°.
In a triangle, the sum of the amplitudes of the angles is 180°. Thus
<CAB + <ABC + <ACB = 180°. You get
<CAB = 180° - <ABC - <ACB = 47°.
40/50?
1.convert the 50 to 100 'cause there are 100 percents in a percent(i just heard that from somebody)
2.50 * 2 = 100 so multiply 40 by 2
3.80,80% is your answer
