Answer:
Number 7 is 48
I think number 5 is 49 I'm not for sure about this one.
Step-by-step explanation:
Number 7:
Since it's a 90 degree angle, you just add 19 + 23 which gives you 42. Subtract 42 from 90 and it gives you 48, the value of the variable.
Number 5:
Now I'm not for sure about this one because of the number 12 pointing to the connecting point. So, I'd rather not say how I did this one before I get you confused when you learn about this in the future.
<u>Answer</u>
1.156 × 10⁰
<u>Explanation</u>
In indexes,
a⁰ = 1 ⇒ ㏒aⁿ = ㏒1
n㏒a = ㏒ 1
n = ㏒1/㏒a
but ㏒1 = 0
n = 0/㏒a
= 0
∴ So to represent 1.156 to the power of 10 it will be;
1.156 = 1.156 × 10⁰
The answer is just 236,000 I hope it helps and is right
