Answer:
Linear pair
Step-by-step explanation:
<1 and <2 lie on a straight line.
Angles that lie on a straight line are considered as linear pair angles.
Linear pair angles sum up to 180°, which is the measure of a straight line angle.
Answer:
y=1
Step-by-step explanation:
the "mx" part of the equation is the slope, since we need the slope to be zero, there won't be anything in the "mx" part. The "+b" bart of the equation is the y-intercept, since we need the y-intercept to be one, the "+b" part will be 1.
Answer:
x= -4
x= 4
Step-by-step explanation:
This is a quadratic equation, and can be solved very quickly since it only has two terms, the square one and the free term.
Hence the solutions is obtained following the steps from below:
x2-16=0
Lets sum to both side 16
x2-16=0+16
x2=16
Now, lets apply square root to whole equation:
The bars means that x can be-4 o 4, since -4^2=16 and 4^2=16
ANSWERS
a. Yes, congruent. By SSS postulate
b. Yes, congruent. By AAA postulate
c. Yes, conguent. By SAS postulate
EXPLANATION
a. Sides MQ and MN are congruent as shown in the diagram. So are sides PN and PQ. Side PM is shared by both triangles so it must be congruent to both.
b. It is shown in the diagram which angles are congruent:
c. Angles DEC and AEB are <em>vertical angles</em> and they are therefore congruent. The two sides that form those angles are shown congruent in the diagram, so we have a side, the next angle and the next side: SAS postulate.
50kg * 1000g/kg = 50,000g
C. 50,000g
