(−5.2)+(−3.8)–{(−1.2)–[(−0.5)–(−0.7)]}
To simplify this problem we will use order of operations. PEMDAS which stands for Parenthesis Exponent Multiplication Division Addition Subtraction
=(−5.2)+(−3.8)–{(−1.2)–[(−0.5)+0.7]}
=(−5.2)+(−3.8)–{(−1.2)–[−0.5+0.7]}
=(−5.2)+(−3.8)–{(−1.2)–[0.2]}
=(−5.2)+(−3.8)–{(−1.2)–0.2}
=(−5.2)+(−3.8)–{−1.2–0.2}
=(−5.2)+(−3.8)–{-1.4}
=(−5.2)+(−3.8)+1.4
=(−5.2)−3.8+1.4
=(−5.2)-2.4
=−5.2-2.4
=-7.6
Hence final answer is -7.6.

Answer:
<h3>x =11</h3>
Step-by-step explanation:
Using the triangular law which states that the sum of interior anggle of a triangle is equal to exterior angle
From the diagram
Interior angles = 5x +10 and 58
Interior angle = 11x+2
Equate both expressions
5x + 10 + 58 = 11x+2
5x - 11x = 2 - 10 - 58
-6x = 2-68
-6x = -66
x = -66/-6
x = 11
<em>Hence the value of x is 11</em>
