Answer:
x = 31
Step-by-step explanation:
13 + 6 + 2x - 18 = 4x - 29
1 + 2x = 4x - 29
30 + 2x = 4x
30 = 2x
15 = x
4(15) - 29
60 - 29
31 is the unknown measurement

The value of the base in the given triangle is 22.96.
<h3>What is a triangle?</h3>
Three edges and three vertices make up the three sides of a triangle, which is a three-sided polygon in geometry. The fact that a triangle's internal angles can be added up to equal 180 degrees is its most significant characteristic. Triangle's angle sum property is what this characteristic is known as.
We have given to find m, we will use cosine rule
cos ∅ = base/hypotenuse
Here ∅ = 35°
Base = m
Hypotenuse = 28
lets substitute the values and we get,
⇒ cos 35° = m/28
⇒ m = cos 35° × 28
⇒ m = 0.82 × 28 ( cos 35° = 0.82)
⇒ m = 22.96
Thus, the value of the base in the given triangle is 22.96.

Answer:
the rectangle is 5√6 wide and 10√6 length
Step-by-step explanation:
The dimensions of the larger rectangle are wide and tall
we know that
The ratio of its areas is equal to the scale factor squared
a = factor of scale
b = large rectangle area
c = original rectangle area
a² = b/c
b = 5 x 10 = 50
c = 6 x 50 =300
a² = b/c = 300/50 = 6
a = √6
the rectangle is 5√6 wide and 10√6 length
