Since the angles are bisecting < RSU = < UST
substitution----- 4x+16=9x-9
subtract 4x from both sides----- 16=5x-9
add 9 to both sides-----25=5x
divide by 5 on both sides------ 5=x
The value of x is 5
substitute the value of x in both expressions
1st expression: 4x+16
substitute the value of x------ 4(5)+16= 20+16=36
2nd expression: 9x-9
substitute the value of x-----9(5)-9=45-9=36
< RST= <RSU+<UST
<RSU=36 degrees
<UST= 36 degrees
------------------------------------you have calculated both above-------------------------------------------
m<RST= 36 + 36=72 degrees
Answer:
320.6
Step-by-step explanation:
<u>Three hundred twenty = 100 * 3 + 10 * 2 = 320</u>
<u>Six tenths: 0.1 * 6 = 0.6</u>
<u />
320 + 0.6
320.6
Answer: 320.6
<u><em>Answer:</em></u>
<u><em>5120 or 2560.One of these</em></u>
<u><em>Step-by-step explanation:</em></u>
<u><em>1. 10*2=20</em></u>
<u><em>2. 20*2=40</em></u>
<u><em>3. 40*2=80</em></u>
<u><em>4. 80*2=160</em></u>
<u><em>5. 160*2=320</em></u>
<u><em>6. 320*2=640</em></u>
<u><em>7. 640*2=1280</em></u>
<u><em>8. 1280*2=2560</em></u>
<u><em>9. 2560*2=5120</em></u>
Answer:
The answer is (C)
Figure A was dilated by a scale factor of 2, with point N as a center of dilation, and then rotated about 90° counterclockwise about N to form figure B
Step-by-step explanation:
∵ Figure B larger than figure A
∴ The scale factor > 1
∵ Figure A is in the first quadrant and figure B is in the second
quadrant and the horizontal side in A become vertical side in B
∴ Figure A rotated 90° anticlockwise
∴ The answer is C
