'How to make the bottom of a div curved with a straight line?

I'm having problems trying to make the bottom of my div to look like this. I tried using border radius to get the curved result at the bottom right but I don't know how can I create this straight line at an angle. Here's my current code.

Check out this code and use the transform property Perspective

transform: perspective(value);

The mention thing is an illustration used as the background image. It would be a good practice if you try it so check out my Codepen Work for source code.

.innerlayer{
  width: 650px;
  height: 400px;
  background-color: #00bcd4;
  margin: auto;
  transform: perspective(1000px) rotatey(18deg);
  border-bottom-right-radius: 35%;
  
}

.outerlayer{
  position: relative;
  padding: 0px;
}

.tophidden{
  width: auto;
  height: 80px;
  background-color: #fff;
  position: absolute;
  top: -80px;
  left: 50%;
  transform: translateX(-50%);
  
}
<div class="outerlayer">
  <div class="tophidden">
<div class="innerlayer"></div>
  </div>
  </div>

I suggest you to use :before pseudo element, and skew it.

Here you can find your modified code

body {
  margin: 0;
}

.navbar {
    // make sure wrapper of pseudo has position: relative
    position: relative;
  
    &:before {
        content: '';
        position: absolute;
        height: 100%;
        width: 100%;
        top: 0;
        left: 0;
        z-index: -1;
        background: linear-gradient(72deg, rgba(100,36,220,1) 0%, rgba(118,107,254,1) 100%);
  
        // set border radius size
        border-bottom-right-radius: 10rem;
        // set skew angle
        transform: skewY(-2deg);
        transform-origin: left bottom;
    }
    

    .container {
        display: flex;
        justify-content: space-between;
        margin-left: auto;
        margin-right: auto;
        max-width: 1270px;
        width: 100%;
        padding: 1.125rem 1.5rem 1.125rem 1.5rem;
    }

    .logo {
