Answer: <u><em>The first no. is 6 and the second no. is 4.</em></u>
Step-by-step explanation: Let the 2 no. s be x and y respectively.
→x+ 2y = 14
<em>→x-y = 2 </em>
<em>∴ x = 2+y</em>
<em>y = y</em>
∴ x+2y=14
= 2+y+2y=14
3y=14-2
3y=12 , y = 12/3=4
∴y = 4
→x = 2+y
= 2+4=6
∴x=6
<u><em>Thus, the first no. is 6 and the second no. is 4.</em></u>
Answer:
Step-by-step explanation:
Since angle ABD is 133 degrees and the sum of the angles in a triangle is 180 degrees, it means that
m∠ DAB + 133 + 22 = 180
m∠ DAB = 180 - 155 = 25 degrees
Also, ∆ ADC is an isosceles triangle because two of its sides are equal. It also means that the base angles are equal. Thus,
m∠ A = m∠ B
Therefore,
m∠ A + m∠ B + angle D = 180
m∠ A + m∠ B = 180 - 22 × 2
m∠ A + m∠ B = 180 - 44 = 136
m∠ A = m∠ B = 136/2 = 68 degrees
m∠ CAB + m∠ DAB = m∠ A
Therefore,
m∠ CAB = 68 - 25 = 43 degrees
Since ∆ ABC is isosceles, then
m∠ CAB = m∠ ACB
m∠ ACB = 43 degrees
m∠ ABC = 180 - (43 × 2) = 180 - 86
m∠ ABC = 94 degrees
m∠ BCD = 68 - m∠ ACB
m∠ BCD = 68 - 43 = 25 degrees
The correct answer is D because the z cancels each other out
think of it this way: -1z +1z=0
place a number in front to help you remeber there is a 1 in front of the variable
