Okay when subtracting 2 negatives the number will be come positive. Using this question ur new equation will be
5+3.8+1.5. You just type in your calculator and get your answer.
The answer is 10.3! Hope this helped!
Answer:
Step-by-step explanation:
Recall that, in this case, the subset of X for which R is defined is called the domain of R. The mistake occurs when we assume that the domain R is the whole set X, but it could happen that R is not defined for some elements of X.
Recall the following example:
X = {2,4,6}.
We can define R as follows {(2,2), (4,4), (2,4), (4,2)}. We can easily check that this is a transitive and symmetric relation, but since we don't have the element (6,6) it fails to be reflexive.
Answer:
Always.
Step-by-step explanation:
Congruent means equal in mathematics. And equilateral triangles' sides are <u>always</u> equal. Therefore, always is your answer.
Answer: 87°
Step-by-step explanation:
Sum ange of a supplementary triangle is 180°
Therefore, to get the measure of the largest angle, we add the angles together and equate to 180 to get the value of x first.
18x - 7 + 12x + 9 + 4x = 180°
34x + 2 = 180°
34x = 180 - 2
34x = 178
Divide through by 34
x = ¹⁷⁸/₃₄
x = 5.24.
Now substitute for x to get the measure of the largest angle.
i. 18(5.24) - 7 = 87.32,° to the nearest degree = 87°
ii. 12(5.24) + 9 = 71.88°, to the nearest degree = 72°
iii. 4(5.24) = 20.96, to the nearest degree = 21°
The largest angle is 87°
