The correct answer would be two corresponding sides and two corresponding angles are congruent.
Step-by-step explanation:
a) The circumference of a circle is 360 degrees. so:
7x+15+8x+6x+30=360
21x+45=315
21x=135
x=<u>15</u>
b) This means 7(15)+15=120, 8(15)=120, and 6(15)+30=120. Thus, by the inscribed angle theorem, all the angles measure 60 degrees, and the triangle is thus <u>equilateral</u> and <u>isosceles</u>.
Answer: d= 412
i did 267+145 and that was 412 then i did 212-267 and got 145
Answer:
The option A) -4-3i is correct
Therefore the simplified given expression is (-1-6i)+(-3+3i)=-4-3i
Step-by-step explanation:
Given that the expression is (-1-6i)+(-3+3i)
To simplify the given expression as below :
(-1-6i)+(-3+3i)=-1-6i-3+3i
=(-1-3)+(-6i+3i) ( combining the real parts and imaginary parts separately and adding the like terms )
=-4+(-3i)
=-4-3i
(-1-6i)+(-3+3i)=-4-3i
Therefore the simplified given expression is (-1-6i)+(-3+3i)=-4-3i
Therefore the option A) -4-3i is correct
I can not really explain it I just know it. the answer I do believe is 3,000
