Answer:
A) because b=c it is an equlateral triangle.
The interior Angles of a triangle is always equal to 180 .
Therefore 180-38 =142
because B=C
142÷2 =71
Answer:
60
Step-by-step explanation:tanI=

\tan I = \frac{6.7}{3.8}
tanI=

6.7
I=\tan^{-1}(\frac{6.7}{3.8})
I=tan

I=60.44\approx 60^{\circ}
I=60.44≈60

The answers to all the subparts of the multiplication problem are shown:
- 185 × 24 = 4440
- 1288 × 33 = 42504
- 6301 × 47 = 296147
- 3440 × 75 = 285000

What is multiplication?</h3>
- Multiplying in math is the same as adding equal groups.
- The number of items in the group grows as we multiply.
- Parts of a multiplication issue include the product, the two factors, and the product.
- The factors in the multiplication problem 6 x 9 = 54 are the numbers 6 and 9, and the product is the number 54.
So, multiplication of the numbers:
- 185 × 24 = 4440
- 1288 × 33 = 42504
- 6301 × 47 = 296147
- 3440 × 75 = 285000
(Refer to the images attached below for calculations)
Therefore, the answers to all the subparts of the multiplication problem are shown:
- 185 × 24 = 4440
- 1288 × 33 = 42504
- 6301 × 47 = 296147
- 3440 × 75 = 285000

The value of x the function when x = -7.5 is 34.5
<h3>Functions and values</h3>
Functions are written in terms of variables
Given the expression –3.8x + 6, when the value of x is -7.5, hence;
f(x) = –3.8x + 6
f(-7.5) = -3.8(-7.5) + 6
f(-7.5) = 28.5 + 6
f(-7.5) = 34.5
Hence the value of x the function when x = -7.5 is 34.5
