Answer:
X=2
Step-by-step explanation:
You can prove the triangle congruent by SAS. First, reflexive property and then isosceles triangle theorem since two side is congruent, the opposite angle is congruent to each other because of that theorem and then cpctc
Answer:
sin xy / x = 0
Step-by-step explanation:
thay x = 0 và y = 3 vào sin xy / x ta có:
sin (0*3) / 0 = sin (0) = 0
Answer:
x=13 degrees
Step-by-step explanation:
Since m is parallel to l, 119= (9x+2)
119=9x+2
Subtract 2
117=9x
Divide by 9
13=x
Answer:
None of the above
Step-by-step explanation:
15/45=1/3
<em>when we solve the equation it will become
x</em>² + 9x<em>= 0
now here a = 1 , b = 9 and c = 0
by using quaderatic formula
x = -b +,-</em>√<em>b </em>²<em>- 4ac / 2a ( 2a is divided by all terms )
by putting values
x = - 9 +,</em><em>- </em>√<em>81 / 2(1) ( </em>√<em>81 = 9)</em><em>
x = -9 + 9 / 2 and x = -9 -9 /2
x = 0 and x = -18 /2 = -9
now there are two values for x one is- 9 and other is 0
so we put -9 as the value of x then answer will be zero..</em>
