Answer:
55 degree
Step-by-step explanation:
90 +35+missing angle=180 sum of all angles of triangle is 180
so. missing angle =55 degree
Answer:
19
Step-by-step explanation:
The equation has "absolute value" , "addition", "subtraction", "division", and "multiplication", and "parenthesis".
The order we follow here would be:
PEMDAS, which is "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction"
Also, note, we can do absolute value first, before these.
Now let's simplify using PEMDAS:

So the answer is 19 (note: i used "/" sign for "division")
Answer:
B. 4
Step-by-step explanation:
Given :

The logarithm function can be converted to an exponential function as
can be expressed as ![[a^c=b]](https://tex.z-dn.net/?f=%5Ba%5Ec%3Db%5D)
Similarly for the given expression

We can write,

Using property of negative exponents ![[a^{-b}=\frac{1}{a^b}]](https://tex.z-dn.net/?f=%5Ba%5E%7B-b%7D%3D%5Cfrac%7B1%7D%7Ba%5Eb%7D%5D)

So we can write that as:

Writing the exponents in radical form as ![a^{\frac{b}{c}}=(\sqrt[c]{a})^b](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7Bb%7D%7Bc%7D%7D%3D%28%5Csqrt%5Bc%5D%7Ba%7D%29%5Eb)

Taking cube root both sides to remove the cube.
![\sqrt[3]{(\sqrt{x})^3}=\sqrt[3]{8}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%28%5Csqrt%7Bx%7D%29%5E3%7D%3D%5Csqrt%5B3%5D%7B8%7D)

Squaring both sides to remove square root.

∴ 
Answer:
90
Step-by-step explanation:
Evaluate x^2 + 2 x^2 + 3 x^2 + 4 x^2 where x = 3:
x^2 + 2 x^2 + 3 x^2 + 4 x^2 = 3^2 + 2×3^2 + 3×3^2 + 4×3^2
3^2 = 9:
3^2 + 2×9 + 3×3^2 + 4×3^2
3^2 = 9:
3^2 + 2×9 + 3×9 + 4×3^2
3^2 = 9:
3^2 + 2×9 + 3×9 + 4×9
3^2 = 9:
9 + 2×9 + 3×9 + 4×9
2×9 = 18:
9 + 18 + 3×9 + 4×9
3×9 = 27:
9 + 18 + 27 + 4×9
4×9 = 36:
9 + 18 + 27 + 36
