Giving brainliest for who gets it right

Answer:

$35$

Step-by-step explanation:

From the information given we can solve for x using the larger triangle

we know that the angle at the top is 45 degrees and the side opposite of it is 35, in other words we need to find the adjacent, or rather, x

Since we have angle, an opposite side, and we need the adjacent. The trig function we need to use is $tan$ , the formula is

$tan0$ $=\frac{opposite}{adjacent}$

we need to rearrange this to solve for the adjacent

$adjacent=\frac{opposite}{tan(0)}$

$x=\frac{15}{tan(45)}$

$x=35$

plz mark me brainliest. :)

An isosceles triangle has two sides of equal length, a, and a base, b. The perimeter of the triangle is 15.7 inches, so the equa

ivolga24 [154]

2 a + b = 15.7
Since the sides are equal length, the equation is:
2 · 6.3 + b = 15.7
We can solve it:
12.6 + b = 15.7
b = 15.7 - 12.6
b = 3.1 cm
