The number 3 is in the tens place so you look at the 4. It is not higher than 5 so your answer is 930
I know nvm I do not it’s so hard
Answer:
A. Congruent angles have the same measure.
Step-by-step explanation:
In geometry, 2 objects are congruent if they have the same shape. As such, congruent angles are formed from such shapes. Irrespective of the unit of measurement (in degrees or radians), congruent angles are equal.
This is independent of the direction of the angles.
Hence the right option is
A. Congruent angles have the same measure.
From 1st condition:
3^(x+1)=81
Take log on both sides,
➡ log [3^(x+1)]=log81
Use the property: log(x^a)=a logx
➡ (x+1) log 3=log(3⁴)
➡ (x+1) log 3=4×log 3
➡ (x+1)=4 (log 3 /log 3)
➡ x+1=4
➡ x=3➡↪➡↪ ANS
From 2nd condition, (Same process are repeated)
81^(x-y)=3
➡ 3^4(x-y)=3
➡ log [3^4(3-y)]=log 3
➡ 4(3-y) log 3=log 3
➡ (3-y)=(log 3)/(4log 3)
➡ 3-y=(1/4)
➡ y=11/4 ➡↪➡↪ ANS
I might be wrong.
I guess that in total all the angles equal to 180, that being said...
m∠BAC = 79
