Answer:
<DEB= 125 degrees
Step-by-step explanation:
To get this, you would need to know all 2 angles of the triangle.
To find the first angle, simply do 180-107 to get 73(because supplementary angles add up to 180 degrees).
Next, 180-52(given angle)-73 to get 55 because the 3 angles of a triangle add up to 180(triangle angle sum theory).
You would see that <DEB is part of another supplementary angle so, do 180-55 to get 125.
<DEB=125 degrees.
The answer is z = 3 + i
z = a + bi
conj(z) = a - bi
conj(7 + 3i) = 7 - 3i
<span>(conj)z + 2z = 2 + 4i + conj(7 + 3i)
</span>a - bi + 2(a + bi) =<span> 2 + 4i + 7 - 3i
</span>a - bi + 2a + 2bi =<span> 2 + 4i + 7 - 3i
</span>3a + bi = 9 + i
From here:
3a = 9 and bi = i
a = 9/3 b = i/i
a = 3 b = 1
z = a + bi
z = 3 + 1 * i
z = 3 + i
Answer:
18
Step-by-step explanation:
Write the expression
-2x²y
substitute the real values with x=-3 and y= -1
-2(-3²)×(-1)
-2(9)×(-1)
-18×-1

Answer:</h3>
96,767,921
<h3>
Step-by-step explanation:</h3>
5 - 7 + 2 - 6 ÷ 2 + 24^3 * 7000 - 76 = 96,767,921
Exponentiation is performed first, followed by multiplication and division in their order of appearance.
= 5 - 7 + 2 - 6 ÷ 2 + 13,824 · 7000 -76
= 5 - 7 + 2 - 3 + 96,768,000 -76
Then addition and subtraction are peformed in the order of appearance. (The commutative and associative laws apply.)
= (5 -7 +2) +96,768,000 -3 -76
= 96,767,921

A Google or Bing search box will evaluate an arithmetic expression strictly according to the order of operations. Your result is attached. The preferred symbols are * (asterisk) for "times" and / (slash) for "divided by". The usual ^ (caret) is used for "to the power of." If you intend grouping, parentheses are required.
