Answer:
Step-by-step explanation:
4x-6y=21
divide by 21
Using sin law;
sin A/ a = sinB/ b
where A = C or 90 degrees; a = 21
B = ? , b = 8
solving for b;
sin(90) / 21 = sin(B) / 8 ; B = 22.39 degrees
Total angle of triangle = 180
180 - 90 - 22.39 = x
x = 67.607 degrees
The angle of measure 1 is equivocal to its adjacent angle, so M<1 = 39 degrees
Because the summation of all angles of a triangle need to be 180 degrees, we can find M<3. We have an angle of 39 degrees and a right angle which is 90 degrees.Therefore M<3 is equal to 51 degrees
Answer:
2x
Step-by-step explanation:
when the base is the same, we subtract when dividing, so
3-2=1, 2x^1=2x
2x^2-12x+18 this is the answer from my friend
