Percent change = ((new value) - (old value))/(old value) × 100%
= (180 -135)/135 × 100%
= 33 1/3%
180 is about 33% greater than 135.
Answer:
Answer is 71.95°
Step-by-step explanation:
Cosine formula is
a^2=b^2+c^2-2bc(cosA)
cos A =b^2+c^2-a^2/2bc
if a= 119,b=94,c=173
cos A=94^2+173^2-119^2/2(94*173)
=8836+29,929-14,161/2(16,262)
=38765-14,161/32,524
=24604/32,524
=0.7564
cos A=0.7564
cos^-1=40.85°.that's for angle A.
Using the same formula
B=31.1°
C=180-(40.85+31.1)
C=180-71.95
C=108.05
Since angle on a straight line is 180
therefore x is 71.95
Also the sum of angles A and B
A. The function must be non-linear because he constantly changes his speed and pauses at some places. For it to be linear he would have to be going at a constant rate the entire time.
B. Plot the point (20, 1.2), draw a line from (0,0) to it. Then plot (30, 1.2), because he stays there for 10 minutes. Now plot the point (60, 2.5) because it takes him 30 minutes to walk 1.3 miles to the park. Then plot the point (75, 2.5) because he stays there for 15 minutes. Lastly, plot the point (120, 5) for his return home. Be sure to connect these points together with lines.
A = 24+6= 30
B = 24x6= 144
C=24/6= 4
D= (24+6) ^2 = 30^2 = 900
There you go! Please mark brainliest and have a great day :)
Multiply both sides by 39 to get 13=M
