The size of angle aob is equal to 132 degrees and the size of angle cod is equal to 141 degrees. find the size of angle dob.
Varvara68 [4.7K]

angle AOB = 132 and is also the sum of angles AOD and DOB. Hence 
angle AOD + angle DOB = 132°    ---> 1 

angle COD = 141 and is also the sum of angles COB and BOD. Hence 
angle COB + angle DOB = 141°    ---> 2

Now we add the left sides together and the right sides of equations 1 and 2 together to form a new equation. 

angle AOD + angle DOB + angle COB + angle DOB = 132 + 141       ---> 3 

We should also note that: 
angle AOD + angle DOB + angle COB = 180° 

Therefore substituting angle AOD + angle DOB + angle COB in equation 3 by 180 and solving for angle DOB:
180 + angle DOB = 132 + 141 
angle DOB = 273 - 180 = 93°

Joni said that she could rewrite the expression d^3•d^11 as d^33. What mistake did Joni make?
Rudik [331]

Answer:

Joni's mistake was to multiply the exponents instead of adding the exponents.

Step-by-step explanation:

we know that

When multiplying two powers that have the same base, you can add the exponents

so

d^{3} *d^{11} =d^{3+11}=d^{14}

Joni's mistake was to multiply the exponents instead of adding the exponents.
