Answer:
∠A = 45°
Step-by-step explanation:
◺ABC is a right angled triangle.
Sum of interior angles in a triangles is 180.
∠A + ∠B + ∠C = 180°
∠A + 90° + 45° = 180°
∠A = ( 180 - 90 - 45 )°
∠A = 45°
Note : -
□ is 90°
Answer:
yes
Step-by-step explanation:
Each input has one corresponding output.
Id say 1/2. Its tossed twice and could go either way.
The word can be represented as a set and in the roaster form the set of letters is {s, a, l, t}
<h3>What is set?</h3>
A set is a collection of clearly - defined unique items. The term "well-defined" applies to a property that makes it simple to establish whether an entity actually belongs to a set. The term 'unique' denotes that all the objects in a set must be different.
We have given letter:
"salt"
Here, no letter is repeated.
So we can write it as roaster form:
Let's denote the set as S
S = {s, a, l, t}
Number of element in the set = 4
We can make new set from it if the set has only vowels
S(v) = {a}
If set has only consonants:
S(c) = {a, l, t}
Thus, the word can be represented as a set and in the roaster form the set of letters is {s, a, l, t}

<span>In this triangle, the product of sin B and tan C is c/a or cos B, and the product of sin C and tan B is b/a cos C. We determine these as follows:
</span><span>sin B tan C = b/a (c/b) = c/a
</span><span>sin C tan B = c/a (b/c) = b/a
Hope this answers the question. Have a nice day.</span>
